Took out Conc Effect and put in GMP just to test. I actually quite like it. Clears EVERYTHING when you crit. Probably best for trash clearing but I mean anything big I'm hitting with puncture anyway so..... Well until I have a better use for the extra mana I'll use it.
Edit: I should say I'm just using it for xp/farm runs. Helps my clear time!
One more thing...
What are you guys using for mobility and CwDT?
Having trouble finding a spot to do lightning warp / reduced duraction / faster casting and I havn't a clue what to run on CwDT. I'm thinking poacher's mark maybe? Not sure if Poachers mark will still grant life on hit with our bow but at least it decreases their evasion....If not Poachers I'd say temp chains just so we can get away heh.
