Demon form.

So, IMO, I loved playing in demon form, but I don't want to play like everyone else—millions of comets from the air. I want deep chaos, but what we have is, hmm, not good. I use few curses, and the main is Hexblast. This build clears T15 and T16 nicely, but the problem is bosses. Which ascendancy supports chaos builds? This will work with demon form and chaos, but we need changes or additions—more curse skills and something in the ascendancy.
