i still only have a basic skeleton of an idea and not an actual build, but it's adaptable enough i can just throw on different spells as they come up in the campaign and see how they feel.
since i'm going Ele with Golem buffs i'll have enough generic damage/aoe/cast speed to do whatever comes up. probably leaning towards either
something with a physical base like Glacial Cascade so i can get the most from quad-Herald
or Channelling, like Divine Ire/WOrb just to see how terrible, or not, it feels

i'm big chillin' not worried about it...
