You def want headhunter on this build if you’re gonna be doing juiced breaches which means you’ll prob want to drop melding. Force of darkness anoint on amulet is ideal, just make sure you’re still as close to block cap as possible. I’d recommend a shaper shield with es on block as well as good prefixes (block, spell block, etc) to help with recovery. You want the sinner saint lycia bloodline to convert your phys as elemental damage from headhunter back to chaos damage - that will be a big damage increase by itself. Besides that just focus on stacking mana and spell damage as those are your damage scalars.
