The Maliwan grip increases elemental effect chances, so I’d go with that instead of a Bandit. The only weapon that needs an increased mag size with Gaige is the Infinity because she can’t use it otherwise.
I have yet to run through OP8 with this particular setup, Im not having time to play properly right now. The damage reduction probably hurts the DoT damage, but I think it can still be relevant. Also, the elemental effect is just one of the pros of this setup.
My playstyle is kinda hybrid. I tend to charge Deathtrap with the proper element for the area I’m running and then play the game properly. The Fibber and the Hail are normally the guns I use for sustainted combat while I always have some gun for when things come close enough. I do use my grenades all the time like I was playing Axton. They are my actual source of elemental DoT. If you get the Storm, you can use it too with great effect with this build. You can even use the Bee with the Storm like you were actually a sniper.
You can use only shock weaponry due to Wires Don’t Talk and Anarchy and still be effective, but it’s better to match elements. I always farm for a shock Pimpernel, Fibber and Hail before starting UVHM so I can play until they are badly outleveled.
Also, starting your game with a Jakobs shotguns like the Triquetra is always good to stack some anarchy until you can swap to your usual guns and still be effective. Pre stacking is boring as hell.
If you find pre-stacking boring do what I do. Get a low capacity Jakobs shotgun, go to the target dummy, aim, put a piece of tape on the firing button and go make some coffee. If you don’t hear Gaige’s Anarchy gain quotes, buy some ammo and repeat the entire process.
EDIT: Added a few more guns in the gear section and a link to a thread in the old forums that made me want to spec in the LBT tree. There you are going to find some more in depth explanation about how the DoT works.
Also, added the fire elemental relic as an option. I’m going to add some tips later
I think that the best definition is Hybrid as it has Deathtrap, DoT and gun damage in focus. I can post it there if you want!
EDIT: Posted some tips and, if nobody has something to add, I think it is done!
Any input is still welcome and thanks for all the comments, likes and views!
I’d appreciate it. I need the other info like specific gear needed, levels, difficulty, etc. Thanks. 
So, as a fan of IO, I’m just poping in to say a little piece for it, the really nice thing about it is that you only need one point to get the full slag chance, and the cool thing is that it actually has a pretty decent chance with one stack, which you can get just durring the reload of most guns. It does get better with more stacks, but not by that much. also, the damage isn’t complete crap like most rank based skills.
Keep in mind that I am saying this all from memory of a thread I read several months ago, but I’m pretty sure I got the gist of it correct.
Edited to fix my stupid. Well…some of it anyway.
But with one stack at 6/5? The max I can invest in it is 1 point for the Legendary Catalyst COM boost, because there is no way I can take points from Electrical Burn, Evil Enchantress or Wires Don’t Talk. In the end, I could only have 6/5 in it and 6/5 in More Pep. If I could slag by a decent chance only with it I could totally sacrifice one point from something or even use the remaining point for it.
Unfortunately, the thread about IO in the old forum is broken 
But doesnt it need to be at rank 10 to slag properly?
I mean, at no point is it going to be your only slag source, it simply takes too much time to use and dosen’t proc on the first shot, I would argue that it is better than more pep though, because more pep is pretty terrible and simply because it adds damage and can help keep stuff slaged or provide you with a way to slag when you’re feeling lazy
Sorry for the delay, Wingsday! Actually, More Pep helps with Electrical Burn procs and this is basically why I favour it over IO.
No worries!
My problem with that is that unless it works differently than every other elemental status effect chance increase, its only increasing the proc chance from 20% to 22% with both More Pep and Electrical Burn at 5/5.
Yeah, the increase is very low. But I usually see it as “a 5% increase in the chance with 10/5 Electrical Burn for 1 point only, why not?”
It sounds better to “gain 1 stack while reloading” in my mind, haha
I don’t know, with the way the math works, I just don’t think More Pep is worth it in most situations. you get much more out of your points elsewhere.
Can’t believe that I didn’t see this thread any earlier.
For More Pep, 2 or 3 points are more than adequate, blame the math behind it.
However, I’m liking it that the Storm gets some love (not a perfect SR by any means but Gaige gets great use out of it).
Thanks!
Everytime I see the pearls I think they were made for specifics VHs. The Storm really shines in the hands of Gaige as the Avenger shines with Axton.
At first,I dont intend to deny your build at all.So please pay no attention to my this post.
What I simply want to say is "BigBoomBlaster is very fun and useful!" 
Sometimes I play with the following build that is focused on DoT-Granade and SR a bit.(In other words, a bit more safe,maybe)
build
*You can move some point on Nth degree into LBT tree.
*Under Op level,this can work very well.
*In op level,this can not work enough.But with multi catalyst,this can.
- Gear(type1)
Slagga
Pimpernel(shock) or Storm
StormFront
BigBoomBlaster
- Gear(type2)
Pimpernel(slag) *good combination with quasar and Nth.
Pimpernel(shock) or Storm
Quasar
BigBoomBlaster
Thanks a lot for the input, neff!! Your work with Gaige is amazing.
About the build, I already use some of them. But I have to try the slag Pimpernel with the Quasar, seems nice enough.
About the spec, I wouldnt change to this. I dont think that Sharing is Caring is amazing without the Flame of the Firehawk shield or Roid in general. I also would lose a lot of points in LBT, my main goal with this setup. Playing through UVHM I only struggled against Badass Rex and Saturn due to my lack of good gear (no good corrosive or explosive guns, nor Gaige top gear like Hail, Pimpernel and Fibber). Commom Teslas were enough to kill stuff with an Evil Catalyst COM and MiS gave DT enough power.
Also, what about One-Two Boom? Is it good in UVHM? I find it hard to hit when my Anarchy is stacked up haha
The bit about 1,2, boom, that is the exact reason I usually don’t take it, I’m not really sure wheather if does a lot of damage or not, it’s been too long. Either way, if you don’t proc it, it does no damage at all.
@nfwp, I was wondering about your skill distribution in LBT, first off, why the points in Shock and Ahhh!? in my experience it doesn’t do that great of damage, you are losing the point that could be in EE, EB, or WDT, and if you’re using snipers you generally don’t want to be that close to your enemies anyway.
Just my thoughts.
Also, I was wondering about your distribution of skill points, it’s been a long time, but on the old forums, somebody did a writeup on Nth degree and found that the first point gives you a 12.5% increase to DPS, while the remaining 4 add up to an additional 12.5% all togather, with that in mind, I would move those points to the LBT tree as well, yeilding something like this. I’ll look for that thread later.
Incedentaly, I’d also take the 5th point in UF rather than MoSS in the BFF tree because I think it is more important, espically with <5 points in BSS.
