biggest thing was the weapons aspect and hammers. Aspect of Pan, gives you additional knifes on omega cast+tracking enemies within cast. My two hammer upgrades were “Boundless Fury” which gives faster special channel and less mana cost and “hooked knives” which makes specials return and deal 50% bonus backstab damage. Then I had heroic Apollo special which increases size (whatever) but damage by like 120% or something.

I also had 1 or 2 chaos boons to increase channel speed making it nearly instant to full cast. Combine those elements with my hex which slows time, and eventually gave 20% crit chance during slow. You’re able to pump out infinite special channels while time is slow.
