[Guide] Overkill Explained

I looked into the Overkill Guardian Rank perk during my analysis of [Guide] Critical Hit Calculation, but quickly noticed this is a topic in its own right. So I did a lot of testing again and this is what I found.

This analysis is not exhaustive and will be sporadically updated in the future. I don’t have all items in the game, I don’t know each and every item and skill interaction, and I’ve got a life to waste by actually playing BL3. But I’m trying to cover all the basics as best I can and I’ll add whatever I test beyond that.

1. Basic Principle

The basic principle is that whenever you kill an enemy, all damage exceeding their remaining hit points will be added to the next gun shot.

To avoid confusion, these are the terms I will be using:

  • Excess Kill: The first kill which will leave behind excess damage.
  • Excess Damage: The excess damage left from the Excess Kill that will be added to the next shot.
  • Overkill Shot: That next shot that will get increased damage from Excess Damage.
  • Overkill Damage: The overall damage of the Overkill Shot.

What counts as Excess Kill: The Excess Kill can be a gun shot, a grenade, a melee attack, an action skill attack… doesn’t really matter, what counts is that it’s the last kill.

What counts as Overkill Shot: Only gun shots (including rocket launchers etc., everything that’s in your gun slots). Damage of melee attacks, grenades, action skills etc. is not increased by Overkill. You can melee and throw grenades, as long as they don’t kill another enemy this will be ignored for Overkill. Excess Damage is preserved for the next gun shot. Note I’m saying shot, not hit. If the gun shot misses, Excess Damage is gone.

You can also wait a long time, reload, switch weapons, travel between maps etc., Excess Damage won’t be lost until you fire the next shot or quit the game.

Overkill “stacks” in the sense that with a more powerful Overkill Shot you may kill an enemy leaving even more Excess Damage, then kill the next enemy with an even more powerful Overkill Shot which will leave even more Excess Damage, etc. until you hit the Damage Cap.

2. Excess Damage Calculation

ExcessDMG = DamageDealt - HitPointsLeft

This is simple enough. The Excess Damage which will be added to the next shot is the number that pops up on the kill minus the hit points the enemy had left. Element and enemy type don’t matter because that’s already covered by DamageDealt – it’s simply the number popping up.

Naturally you don’t know the exact number of hit points left (for my testing I figured out the health amounts of my test subjects), it’s visual estimate then. Less health left = more Excess Damage. There are a few special cases to consider:

Multiple projectiles: When killing an enemy with a multi-projectile weapon (e.g. a shotgun), no more projectiles will hit the enemy than needed to kill them. If e.g. they have 160 health left and you’ve got a shotgun that does 100×5 damage, only 2 pellets will hit them even if they’re standing right in front of you. Examples with this enemy:

A) 100×5 shotgun: DamageDealt = 2 × 100 = 200 >>> ExcessDMG = 200 - 160 = 40
B) 250×2 Q-System: DamageDealt = 1 × 250 >>> ExcessDMG = 250 - 160 = 90
C) 500(×1) sniper: DamageDealt = 500 >>> ExcessDMG = 500 - 160 = 340

Generally, ExcessDMG cannot exceed the damage of a single projectile. The higher the damage of a single projectile, the better for ExcessDMG – which mostly favours single-projectile weapons.

Multi-kill: What if you kill several enemies with one hit, e.g. with a rocket? The game won’t add the Excess Damage of all enemies together, instead it will just take the Excess Damage of one of them. I don’t know how it decides which enemy to pick for this.

DOT: If an enemy is killed by a damage over time effect such as burning, only the last bit of damage that finished them (again, the last number popping up) will be used for Excess Damage calculation, which usually won’t be much.

3. Overkill Damage Calculation

On the next shot, your Excess Damage will be added to the gun’s base damage – before all other bonuses are applied.

OverkillDmg = (BaseDmg + ExcessDmg) × GunDmgBonuses × ElementDmg × CritDmg × …

For example, let’s say our gun has 1000 base damage, Excess damage is 2500, and we’ve got +30% from Personal Space and +20% from Wrath, and it’s fire vs. flesh (× 175%):

OverkillDmg = (1000 + 2500) × (1 + 0.3) × (1 + 0.2) × 1.75 = 9555

Since Excess Damage received all the same bonuses that the base gun damage did, in principle our overall damage was increased by +250% because Excess Damage was 2.5 × base damage.

There’s one exception to this: amp shields. These only boost base gun damage, not Excess Damage. For example, if we add a Re-Router (+120%), we will get (1000 × 2.2 + 2500) = 4700 (before the other bonuses are applied).

Multi-projectile weapons: Excess damage will be distributed evenly among the projectiles (for n pellets, it will be ×1/n for each pellet). This only applies to regular multi-projectile weapons that have “XY×n” gun damage on the card – special weapons that have multiple projectiles without the “×n” mentioned under gun damage (e.g. Bekah, Lyuda) will have full Overkill Damage on every projectile, greatly increasing their Overkill potential.

4. Damage Cap

Overkill can’t be exploited infinitely, there is a maximum damage cap based on the weapon’s gun damage (that’s the gun used for Overkill Shot, not the gun used for Excess Kill) – so forget using 50k excess damage with a lvl 20 gun, that won’t work.

For single projectile weapons it is +400% damage:

OverkillMaxDMG = NormalDMG × 5

However, multi-projectile weapons suffer a severe penalty:

OverkillMaxDMG = NormalDMG × (1 + 4/n)

Where n is number of projectiles. A Q-System (2 bullets) will have max. +200% damage, a 4-pellet shotgun max. +100%, and a 16-pellet shotgun max. +25%. This e.g. means that the Maggie is crap for overkill: being a 6-pellet weapon, it gets max. +67% – while an ordinary Ranger pistol gets max. +400%. As above, this does not apply to Bekah, Lyuda etc. – they have max. +400% on every pellet.

Even though amp shields don’t increase Excess Damage, they do increase the damage cap: the 1000 dmg gun from the previous example is normally capped at 1000 × 5 = 5000 (before other bonuses are applied), but with the Re-router the cap rises to 1000 × 2.2 × 5 = 11000.

The amp anointment (shield capacity added as damage to next shot after shield break) is added to base damage just like Overkill, but it also increases the cap: if the Re-Router has 15000 capacity, the cap will now be (1000 × 2.2 + 15000) × 5 = 86000.

5. Critical Hit

There’s no difference in critical hit calculation, except that instead of NormalDMG × CritModifiers it’s now OverkillDMG × CritModifiers. This means that not only regular damage but also Excess Damage is multiplied, greatly increasing Overkill Damage potential. An Unforgiven does over 10× damage on crits, this will also apply to all the Excess Damage - but you’ll quickly run into the cap because of its low gun damage.

6. Jakobs Ricochet

A ricocheting bullet has no damage penalty, so both enemies will each receive the full package (although the second one won’t be critted most of the time). Headsplosion and Pa’s Rifle can apply it up to 4 times. A Bekah theoretically up to 8 times!

Note about the Excess Kill: If you kill an enemy with a crit and the bullet ricochets to another one without killing them, Excess Damage for the next shot is based on the kill. If the second enemy is killed too, that will be used for Excess Damage. This means that if you’re unlucky, you do a feckton of damage on the first enemy but Excess Damage may be tiny because the ricocheting bullet killed another enemy.

7. Status Effects

Damage over time status effects are affected by Overkill too. The way this works is that damage is increased by the same ratio as the shot itself:

OverkillStatusEffectDMG = NormalStatusEffectDMG × OverkillDMG / NormalDMG

8. Remnant (Amara)

Killing an enemy with gun or action skill creates an orb that seeks out another enemy and damages them – dealing overkill damage with a small splash radius (but without the gun damage Guardian Rank).

RemnantDMG = (RemnantBaseDMG + ExcessDMG) × Element

Where RemnantBaseDMG is the damage stated on Remnant’s card (651 at level 50).

edit: Remnant receives more bonuses than that, it receives a lot of bonuses actually – action skill bonuses, splash damage bonuses, elemental damage bonuses and so on. Now Remnant is something that’s really painful to test – just know it deals a LOT of damage. It regularly deals millions of damage, it easily deals dozens of millions of damage, it sometimes deals 100s of millions of damage and sometimes it exceeds a billion. All with only one point. Just put one point there and enjoy.

One important difference is that it has no damage cap – it can deal millions of damage with only one point invested. Raising base damage by adding more points becomes irrelevant with some good excess damage (and without, it does little damage anyway): if the orb does “only” 100k damage, two more points will only add another 1300 on top of that. So don’t waste points, 1/3 is all you need.

Interaction with Overkill Guardian reward: These two are mostly independent of each other. Think of it like this: you kill an enemy, an orb rises. The orb carries Excess Damage from the kill which it will release on hit, but you also carry the same Excess Damage which you will release on the next gun shot. If you one-shot the next enemy, the (usually higher) Excess Damage from that kill will be carried by both you and the new orb rising from that.

Each orb keeps the Excess Damage from its respective kill, so if both orbs from the example are still in the air, they will do different damage on hit.

The most notable interaction is that if an orb kills an enemy, your Excess Damage will now be based on that kill, because the Overkill Guardian reward is always based on the last kill, regardless of what did the kill.

9. Hollow Point (Guardian reward)

This makes an enemy explode if they’re killed with a critical hit, damaging nearby enemies.

This is another instance of Overkill damage: The explosion’s base damage equals the Excess Damage from the kill. It is always non-elemental.

HollowPointDMG = ExcessDMG × ExplosionModifiers

Where ExplosionModifiers are splash/area-of-effect bonuses, e.g. from Arm(s) Deal.

Interaction with Remnant and the Overkill Guardian reward: Remnant and Hollow Point are completely independent of each other. On a critical kill, explosion and orb will both have the same Excess Damage, not influencing each other in any way. However, if the Hollow Point explosion kills another enemy, no new Remnant orb will spawn from that.

The interaction with the Overkill Guardian reward: similar to what Remnant does, the same Excess Damage used by the explosion is carried by you for your next gun shot. If the explosion kills another enemy, that kill is now used for Excess Damage on the next shot.

So with all three together, you’ll get an explosion based on the kill’s Excess Damage, an orb based on the kill’s Excess Damage – and your next gun shot will be an Overkill shot with the same Excess Damage unless another enemy is killed in the meantime.

10. Damage-increasing Anointments

Damage-multiplying anointments (e.g. +100% damage after action skill end or +300% damage after Phaseslam) synergise very well with Overkill, similar to crit or charge bonuses. Like those, more damage on kill means more Excess Damage, and on the Overkill Shot they multiply all Excess Damage along with normal damage. Especially Amara’s +250% after Phasecast and +300% after Phaseslam anointments synergise extremely well with Overkill.

Bonus elemental damage anointments (e.g. +20% bonus Radiation damage or +50% bonus cryo damage) synergise equally well on the Overkill Shot, all their damage is increased accordingly.

However, for building up Excess Damage they don’t work as well as the damage-multiplying ones, because similar to multi-pellet weapons they don’t deal more damage than needed to kill the enemy. They’re in fact applied one after another, and when the enemy dies, the remaining ones are dropped and don’t contribute to Excess Damage. Thus, Excess Damage can never be more than the instance of damage that killed the enemy.

This also applies to bonus elemental damage from skills like Moze’s Cloud of Lead or Amara’s Forceful Expression – or most notably, Infusion which actually causes problems for Overkill (see the Notable Skills section).

If you’ve got several bonuses of the same element (e.g. you can have 4 fire bonus instances going on at the same time with Infusion, Forceful Expression, and a bonus fire damage gun and grenade): even though their damage is all added together in one number popping up, they’re actually applied one after the other in the same way as different elements. So on a kill, you may (in this case, likely) see a smaller damage number popping up, and the dropped instances again don’t contribute to Excess Damage.

11. Notable Weapons & Gear

This is far from exhaustive, just a few things I’ve tested with reliable results. I will add more once I’ve done more tests.

  • OPQ-System: Alt fire mode spawns a flying gun shooting at enemies. Overkill damage is applied to all its bullets until it disappears.

  • Projectile Recursion: The projectile reflects between enemies, dealing Overkill damage on every hit. Packs of enemies just evaporate even on Mayhem 4. It also deals a feckton of DOT. This weapon is insane by default, but it’s even more insaner with Overkill.

Super critters: Guns with excessive critical hit damage greatly improve Overkill Damage potential, because they turn little base damage into a lot of crit damage, which also applies to Excess Damage. For example, I have a +432% Unforgiven and a Jakobs sniper with ~3900 gun damage and +21% crit damage. They deal almost the same crit damage (15K) and they do 77K/78K at the Overkill damage cap. The big difference is that the sniper needs about 17,800 Excess Damage to reach the cap while the Unforgiven only needs 4,800. Crit killing an enemy with the Unforgiven (regular damage) will in most cases instantly hit the damage cap on the next shot.

  • Unforgiven: This pistol does about × 10 damage on critical hits (depending on parts). The best I’ve ever found is +432%. Sadly, it’s not easy to crit with it because it’s pretty inaccurate and usually doesn’t even have a scope. It’s pretty, uhm, hit and miss.

  • Monocle: Shooting while aiming through the scope multiplies crit dmg by × 3.5 (hip shooting does regular crit dmg). Kind of the opposite of the Unforgiven since its excessive zoom level makes it hard to target anything that’s not very far away.

“Hidden” multi-projectile weapons: As stated above, weapons that shoot multiple projectiles without “×n” mentioned will apply full Overkill Damage on every projectile.

  • Lyuda: Three projectiles.

  • Bekah: Four projectiles. Being a Jakobs weapon, each of the bullets can ricochet to another enemy on crits, so full Overkill Damage may theoretically apply to 8 hits (although that’s highly unlikely).

Damage-multiplying weapons: Some Maliwan weapons are able to multiply the entire damage dealt beyond what’s stated on the card, also greatly increasing Overkill potential. If you compare a 3000 dmg Jakobs sniper to a 1500 dmg weapon of this type that can multiply damage by 2, Overkill Max Damage will be the same but the latter will only need half the Excess Damage to reach it. Maliwan weapons always come with elements, so they can even deal much more damage than that Jakobs sniper.

  • Proton Rifle: Uncharged, this Maliwan sniper rifle does normal damage based on the stats on the card. Fully charged, it will do 2x damage (both impact and DOT), and on top of that it does splash damage – while still using only one ammo. Great for Overkill.

  • Melter: The pistol version of the Proton Rifle. Same effects, but since it’s got lower damage and lacks the sniper rifle crit dmg bonus, you’d probably prefer the Proton Rifle.

  • Ion Cannon: Even though it’s made by Vladof, this rocket launcher can be charged up for more damage, similar to Proton Rifle and Melter – except that it deals ×2.25 damage when fully charged. The interaction with Overkill is the same. With its monstrous damage, this weapon has extreme Overkill potential.

  • Antimatter Rifle: This alien-barrelled Maliwan sniper rifle is like an elemental railgun. What the item card doesn’t tell you is that all damage is multiplied by x2 (like a fully charged Proton Rifle, but the shot is instant). Gun damage, crit damage, status effect damage, Overkill damage, everything is x2. It deals massive status effect damage and hits multiple enemies if lined up, greatly increasing Overkill potential. Main downside: uses 3 ammo per shot.

  • ASMD: Bolt and orb on their own each do damage based on the card stats. The combo however does a big explosion that can hit a whole pack of enemies, and it does x2.5 damage to every target hit, which also applies to Overkill damage.

Shotguns (or similar multi-pellet weapons): These weapons are terrible for Overkill, because they A) have low Excess Damage potential and B) suffer from the Damage Cap penalty mentioned in those sections above.

  • Maggie/Masher: Being basically shotgun pistols, these are very bad for Overkill.

  • Face-puncher: While its damage can be increased a lot by both melee and other damage bonuses, its Overkill potential is very limited because of the 7 pellets. Excess damage can’t exceed the damage of one pellet and Overkill can’t increase its damage output by more than 57%. On top of that it can’t even crit, so this is a bad weapon for Overkill. Even with Amara with a lot of damage bonuses it’s far from the Overkill damage some other weapons listed here can do.

Amp shields: These multiply NormalDMG, but not the ExcessDMG part. Thus, their damage increase is limited for OverkillDMG. However, since the damage cap is based on NormalDMG, they can significantly increase Overkill max damage. A Re-Router (+120%) increases Overkill max damage by x2.2.

12. Other Notable Skills

Far from exhaustive, I’ve only really tested a few so far.

  • Two F4ng (FL4K): Somewhat problematic for Overkill. When procced, adds a projectile to the shot. This e.g. turns a 1000 dmg sniper into a 1000x2 sniper for this shot, triggering all penalties/disadvantages of multi-projectile weapons. If you’re chaining Overkill shots close to the damage cap, Two F4ng may be detrimental.

  • Ties That Bind (Amara): Synergises very well with Overkill. 35% of damage dealt to one of the chained enemies is dealt to every other one, and Overkill Damage increases damage to the other enemies accordingly.

  • Infusion (Amara): Very problematic for Overkill. On the Overkill Shot, there’s no issue, all of it is multiplied. However, it causes problems for building up Excess Damage: since it divides the shot into two separate instances of damage, no more will hit the enemy than needed for the kill, similar to shotguns or bonus elemental anointments. If the 60% main damage is enough to kill the enemy, the 40% action skill element instance is dropped, reducing Excess Damage. Example:
    450 HP flesh enemy, 1000 Dmg non-elemental gun, no point in Infusion. Killing the enemy gives 1000 - 450 = 550 Excess Damage. Now add 5/5 Infusion, and the gun’s primary damage is reduced to 600, which is still enough to kill this enemy, resulting in 600 - 450 = 150 Excess Damage.
    If gun element and action skill element are the same, on hits you see only one number popping up with both instances added together, as if you weren’t using Infusion (60% + 40% = 100%). However, if the 60% instance is enough to kill the enemy, again the 40% one is dropped, resulting in the same loss of Excess Damage.


These are really cool but can you help me with your testing methods, do you have video or screen shots or anything?

Sorry for being skeptical but I know to verify rather than just trust since there is a history of things being missed.

That said I’m really impressed how you are doing these without a target dummy.


Am I understanding this correctly as:

OverkillDMG = NormalDMG + (ExcessDMG × (1 + GuardRank) × Element)

When you say the damage is capped as a function of Normal Damage does this refer to the gun that gained the overkill or the one I’m currently firing?

Eg I use a single pellet weapon with 100 damage and build up to 500 OverkillDmg. I then switch to a new single pellet weapon with 50 damage. Is my overkillDmg still 500 or am I now capped at 250 eventhough I had built up to 500?

I don’t know if this is worth adding but I tested it and did a video, you don’t loose your overkill when you travel between maps. Not that you can build it to crazy levels and go gib a boss but it does help you don’t need to re stack it


An interesting thing I’ve noticed about overkill damage is that it seems like you can substantially increase it by using weapons that charge up to increase damage (ie Proton Rifle, Melter). I have not properly tested this out but I’m consistenly getting crits that do over 400k damage with a Proton Rifle while using Amara (with neutral modifiers).


Yes, correct.

The second gun, i.e. the shot that will inflict the overkill damage on the enemy. If that gun does 50 on a regular hit, it can do no more than 250 with overkill (unless critting, then it’s 250 x crit modifiers).


Well yeah even though overkill is capped it is treated in a way similar to amp but a bit better from what it looks like.

That means you can re amify your overkill damage with crits, skills, elements, etc… and crank it up to crazy levels.


Thanks for the tip, I’ll test that when I have the chance.

I have no videos and at least for this one I haven’t made screenshots. It’s understandable and probably for the better to be sceptical as there’s so much misinformation about BL mechanics on the internet. All I can say is that I put a lot of care in my testing and will only post formulas once they exactly predict in-game results in many situations. But I’ll make some screenshots for this.

My testing is mostly done in The Drought in normal and/or TVHM (whatever’s good for testing), with the skags to the left and/or the bandits up the mountain to where you find Vaughn. I first test the absolute basics until I’ve found the formula for that, and slowly work my way up adding more stuff to the formula until it reliably works too, then add more etc. and test it with different items and skills and so on. I don’t tolerate deviations of more than +/-1 (absolute value, not %) between formula and result, and I don’t use values exceeding 10k because the game rounds down to 1000 so it’s impossible to check if it’s correct.

In this case, a target dummy wouldn’t help for figuring out Overkill anyway. For this one I figured out enemy health (e.g. ca. 89, 99 and 110 for basic level 1-3 bandits) by using level 1 weapons and by repeated incorporation in these formulas with reliable results.


That is tedious work, thank you for doing it. You are a saint.

Yeah its hard to know what to believe or not, you showing the numbers does help a lot. So again thank you.

I can tell in your write ups.


Thank you for doing this. Really helpful.
Thank you Doc, much appreciated and its very time consuming doing all of this. I appreciate you good sir! :acmaffirmative: @DocStrangelove
Thank you… @Derch I saw your vid, very well done. Thanks for all you do. : )
Love this community too much. :innocent:


Made a few screenshots and will add the formulas. For simplicity’s sake I used no skills, class mods or artifacts, so there’s no modifier besides +10.34 gun dmg and +6.35% crit Guardian ranks:


I’ll do 4 different weapons, first showing the item card, then pictures from three situations with formulas each. First image is NormalDMG, second image is the Overkill shot after that, and third is maximum overkill damage (I shot bandits in the face with a strong Jakobs sniper for a lot of excess damage that will exceed the cap).

A) Jakobs rifle, damage = 1116


Level 1 Psycho = ca. 89 health

NormalDMG = 1116 × 1.1034 = 1231.39
ExcessDMG = 1231.39 - 89 = 1142.39
OverkillDMG = 1231.39 + 1142.39 × 1.1034 = 2491.90
OverkillMaxDmg = 1231.39 × 5 = 6156.95


B) COV pistol, incendiary, damage = 221×3


Level 1 Psycho = ca. 89 health (only 1 bullet will ever connect), flesh (×1.5 el. mult.)

NormalDMG = 221 × 1.1034 × 1.5 = 365.78
ExcessDMG = 365.78 - 89 = 276.78
OverkillDMG = 365.78 + 276.78 × 1.1034 × 1.5 / 3 = 518.48
OverkillMaxDmg = 365.78 × (1 + 4/3) = 853.49


C) Masher, damage = 454 × 5


Level 1 Psycho = ca. 89 health (only 1 bullet will ever connect)

NormalDMG = 454 × 1.1034 = 500.94
ExcessDMG = 500.94 - 89 = 411.94
OverkillDMG = 500.94 + 411.94 × 1.1034 / 5 = 591.846
OverkillMaxDmg = 500.94 × (1 + 4/5) = 901.692


D) Dahl rifle, damage = 514, semi auto mode = × 1.2 gun damage. This time with critical hit on overkill shots (but not on the first, normal DMG one)


Level 2 Psycho = ca. 99 health

NormalDMG = 514 × 1.2 × 1.1034 = 680.58
ExcessDMG = 680.58 - 99 = 581.58
OverkillCritDMG = (680.58 + 581.58 × 1.1034) × 2 × 1.0635 = 2812.52
OverkillMaxCritDMG = 680.58 × 5 × 2 × 1.0635 = 7237.97



Note: Deviation of up to 1.95 is most likely caused by gun damage being rounded on the card. If you e.g. put 1115.6 instead of 1116 in the formula, or 220.6 instead of 221, the results are exact.


Thank you for this and I think I get it despite the info overload, but let me see if my fragile mind can grasp this in a more basic way.

So basically what you’re saying is (from my understanding):

Here’s a LOT of numbers and info on how the Guardian overkill perk works, for those new to the game.

For the BL “vets” it is the Krieg/Wilhelm overkill skill, minus stacks and additional OK perk modifiers…but WAIT! THERE’S MORE! Unlike those VH skills, this one doesn’t have a timer so you can take your time to make the shot count. You also get this one’s stored bonus wven if you map-transition between shots.

Yeah, that’s correct. The principle is similar, but I have no idea how those skills exactly worked in BL2/TPS (never looked it up or looked into it myself).

Sometimes I’m too tired for action, and I’m a bit of a maths nerd and I like logic puzzles and figuring out how stuff works. If that may actually help me and others to get a better understanding of what to do in the game, then for the better. I’ve found an actual use for maths! I can’t deny there’s some satisfaction in having a very long formula in my calculator app, inserting the gun damage from the item card so it results in 8247.2 and then I try it in the game and 8247 pops up. Boom gotcha!

It started when I was playing Dragon Keep for the umpteenth time and still I wasn’t sure how to best deal with skeletons. Are they vulnerable to corrosive? To explosive? What’s best? After such a long time I was still uncertain and switched back and forth until I decided to make a spreadsheet of how every skeleton type reacts to every element to settle it once and for all. And then I edited the Wiki pages for all of them to replace the “seems like”/“feels like” misinformation with hard facts.

Later I wanted to know the exact values for Krieg’s melee bonus and couldn’t find it anywhere on the internet. In a few places there was correct information for certain situations but not the exact formula. So I decided to figure it out, did that and put it in the Wiki too. It’s since become a little hobby of mine.


I used to do that in bl2 with a calc I made. It was nice to plug it all in first, shoot and it matches. Even more when I had so many things, full skill tree, com, relic, bar, elemental matching, critical hit, splash damage, and op8 damage reduction and still have it match.


About the charge weapon thing: I tried some Melters and Proton Rifles I found (also some other Maliwan weapons, but it only worked with those two). It seems that they act like regular weapons if you don’t charge them at all, but fully charging them multiplies the entire damage by 2, which includes overkill damage. Add a lot of damage/crit bonuses and matching element and it’s going to hurt. I’ll update the article after more thorough testing.

I’ll also look into amp damage, forgot about that.

I am not a math person, like Krieg in that respect. However after reading your main post and now the quoted part, it made me think of something.

There is a unique pistol, the Dead Chamber, that has a 50% chance at firing an amped shot.

Not sure how best to test it. However it would be interesting to know how well it’s amped shot stacks with an amp shield. As well as how that combo would work with your whole overkill equations.

However it may not be that feasible since it is only a 50% chance at the Dead chamber’s amp shot, and it is the same color affect of an amp shield’s amp shot. So it may be hard to tell if it kicks in, or the amps may not stack.

Besides it is just 1 weapon. So I am not saying you should test it. I just figured I would share my random thoughts on it.

I haven’t made any screenshots again because I find it hard to find the time, but I may do so for this or that in the future. I intend to do formulas and screenshots for maximising Overkill damage because that’s probably the most interesting part.

Sidenote: I found another inaccurate skill description while testing: Amara’s Tempest says +6% per rank elemental damage and an additional +4% for shock, for up to +50% with shock and +30% with other elements. In fact the additional shock bonus is only +2% per rank, so it’s up to +40% with shock and +30% with other elements.
