I tried a few more shots tonight but every time he sighted in the middle of my conduit and then it *** my run. (using Ifrit)
I tried something different using shiva, starting off with rush > shattersoul > darkness > conduit > HS spam. (I have 5/5 in HS) The first 2 MB'd for 17.something thousand but the rest fell off drastically in the 3 to 5k range...
Best I managed was 30% then trust dying and ***hitting the fan.
I guess I'll put this on the side for now till I get more job points.
