Big Bang: The Ugly Truth

Yeah, the same thing with the knockback canceling happens with pierce too, it's really annoying. You'll just have to fire it off early or wait to see if you get hit or missed.

Also, I don't think big bang will end up as archmages' only decent mob skill, it's more of a thing to use when going up a rope, jumping down, or going through a warp, things that put you inside a mob of monsters since if you just tried to use it normally, you'd have to walk into mobs while charging or only make use of half its range.
