Arcane Power bug or WAI?
Should be a bug… Make sure you don’t have any over time effects going on when you test it. Their tick would also count for the Arcane Power
I tested it out with shooting fireballs and after the second fireball it stopped giving me crits. Also I don’t think DoT’s are affected by AP
It is a bug with Arcane Power. On the positive side, if you use a single spell after casting Arcane Power, it will apply to 4 full ticks of damage (regardless of number of targets) plus a fifth tick on a single target.
Hence giving birth to the Energy Surge+AP+Glyph of Storms, 4s AoE immobilize+blind. (you need others to actually kill the targets though, as you can’t deal damage to anything without immediately invalidating AP)
Still, I would just like to see AP work for the five next hits like it used to do in BWE2.
