My blues TP build (which im not worried about), has 492 Acc which I know though kparser caps acc on when building lights
Sorry I have no idea about blu, but I imagine to land multi hit spells (physical) you would need same amount of acc.
Weather or not single hit spells get the same acc boost single hit ws' get, I'm not sure.
Sorry I'm not much help.
Basicly, I would drop a few pieces, till your TP set is just below cap, then bingo, you know how much you need. Edited, Oct 26th 2010 5:28am by Jkrffxi
