This is our list of Elementalist builds for Path of Exile’s Expedition league (3.15). The Elementalist is one of the strongest ascendancy class choices if you want to play a Cold, Lightning, or Fire caster. This class specializes in proliferating very strong Freeze, Burning, and Shock effects to whole packs of monsters. It also has very nice perks for all the elemental Herald skills. The Elementalist can even summon strong Elemental Golems to fight on her side.
