(I'm brand new to the game and would love any advice on the best ways to improve my gear)
@GwaveWobber I'd gander a guess around 240mil, not counting your Leorics. I'd obviously say that's what you need to replace, but I'm assuming you use that simply for leveling.
Your build suggests Archon, but your gear says CM. I'll assume you're primarily a CM wiz due to Chants set. With that in mind, you need more APOC and LoH. A Storm Crow could address both, while a new Chants Force could get you APOC, and you get LoH on an ammy or ring. Chances are you have other rings that help with that.
@Booby, Yeah I have all that stuff. I have a kinda archon gear setup and a straight up CM/WW gear set up. I'm broke so I can't really go all out on both lol.
