better deadly dose (still untested)

the modules are mostly for fashion, it just so happens that they are mostly agility.

I don't own the catalysts so I can't test it myself right now, but a lesser version with different and weaker catalysts got to abyss 50 on fighter, so make of that what you will. Even then, I only stopped at 50 because I didn't feel like trudging through the single digit damage on the bosses with modifiers. It still handily takes on the fodder up to that level. But again, it was in fighter difficulty, so whatever that equals in wrangler I guess.

Obviously the "better" perk selection would be something like deadly dose, corrosive bile, and something like vampiric for healing, but I found the invisibility to be quite useful. More so with the healing from cloaked chrysalis. The invisibility lets you just run through the "linear" levels as you might call them, and the defensive ability cools down fast enough that you can just spam it. Essentially allowing for endless invisibility.
