PoE Scion, Spell Totem, Fire builds

Hello All I finally created a Scion Spell Totem Build and I thought going Hierophant and Chieftan made the most sense even though it seems like most people dont do that for Scion Totem Builds. Anyways here is my pastebin: Im using purifying flame with Soul mantle as my main ability. Obviously im using 2 Kikazaru and took sanctum of thought so that curses have 0% effect. Im using Devouring Diadem for my auras and feast of flesh is a solid help with overall sustain plus its super cool and ive been wanting to use it for a while. E
