Arc Necromancer

By | January 5th, 2018 | Categories: Path of Exile Builds, Spellcaster Builds

No other class that can spam like the witch. Taking up that trait up a notch is the Arc Necromancer, which is all about thunderbolts and lightning hitting multiple targets, bouncing around the map. It’s super-cheap to build, easy to use, and fun. It’s not the best damage-dealer there are thanks to lightning’s wide damage range, and it doesn’t do well with endgame bosses, but the fact that it’s enjoyable to play makes up for it.
