So I've mostly reached the endgame with the build I planned for this league and wanted to show the results off.

Concept is pretty simple: Stack flat mana to get massive added damage through manastorm, arcane cloak and mind of the council. Stack totems to get one of the last sources of massive % mana regen. Use mom+agnostic for defence since you have so much mana already.

Phase run on leftclick for regular manastorm triggers. Can do it manually for more safety, but that's effort. Can definitely be scaled further with more investment.
