Bonus Fireball from Electric Discharge?
I posted the same kind of bug note/complaint here re Electric Discharge, a few days ago. I don’t think it’s useless IF you want it to happen, i.e. have something targeted, but when you don’t have it targeted and it randomly decides to zap a moa or whatever, then it becomes a liability you have no way to get rid of. Then again, this can sort of be said for all(?) the 15pt Ele bonus effects, save that Air’s has a fair range while the others are local.
As for the extra fireball, this happens to me every time I switch between Air and Fire, as well—always get the #1 one extra time after being reattuned. I don’t notice this with other attunement switches, though I don’t use earth/water nearly as much so I may just have missed it.
