Hey, @layenem, thanks for making this post. I realise it’s going on for 20 months old now, BUT(!) I have the same query. My understanding (reckoning) is this; basically it would read better if there were line breaks before the penultimate and final sentences. And also if they hadn’t confusingly used the word “unique” twice in the same paragraph to refer to two different concepts. E.g. if you replaced the second usage of “unique” with “stack type”.
So for example;
For each stack of Interplanetary Stalker, they and their pet gain a bonus to all damage dealt.
Additionally, they gain a unique stacking bonus depending on the type of enemy killed.
Each [stack type] bonus can stack up to three times.
Each stack decays after a short time.
So, first things first, everything listed is a “bonus”, and each “bonus” can stack up to three time. I.e. For every kill, a damage bonus of +10%, up to max 3 stacks. And on top of that, if those three kills were human, then the +15% action skill damage is also x3 for the duration of those 3 three stacks.
If the stacks decay is 30 seconds(?) and you killed those 3 humans in 10 seconds, you have a remaining 20 seconds before the first stack wears off and so on.
If 10 seconds later you’ve killed 3 robots;
- Your max stacks are still at 3, so the standard-damage bonus is still +30%.
- You’ve got 10 seconds left of the 3 stacks of bonus action skill damage from the human kills
- And now you have 3 fresh “additional” bonus stacks of the robot kill corrosive damage for 30 seconds.
- 10 second later with lets say no kills, and the human kill bonus stacks have worn off, but you’ve still got 20 seconds left of robot bonus stacks.
The only thing I’m unsure of (except for still being unsure of the whole thing), is whether the original +10% damage bonus stacks (from the human kills in the scenario above) wear off after those original stacks decay, leaving with you with no standard-damage bonus and only the robot/corrosive damage bonus, or whether the new damage stacks overwrite the old? I guess it must be the latter.
- Get a kill?
- Fresh damage and pet stack.
- No matter what.
- Fresh stack.
- Then additional bonuses stack and decay in their respective rights.
I originally wrote this skill off when I first started playing, which I did with a FL4K/Rakk build. Then I moved onto the other two Action Skills/Trees. However, I’m just coming back to it now, and I’ve realised this skill is only really worth anything when you stick 3 points on Big Game. Not so much for the additional 30% damage boost (which is nice), but for the time bonus. Because in the example above I used 30 seconds, but I’m pretty sure it’s closer to 10 or 15. Which means unless you’re in a slaughterhouse, you’re rarely getting full effect. But once you extend that decay window, you really notice the difference as you go into battle after kills 1, 2, 3, and then you’re in! Let’s GO! Especially if one of those kills was a badass and you’ve doubled down on TMDG.
Anyway, thanks for the OP. Writing this all down has been helpful and cathartic for me at least, even if it just sounds like ramblings to every else hahah.
