Path of Building
I stumbled across Blade Blast of Dagger Detonation while trying to squeeze some DPS out of my PF brand build (don't recommend). This skill has insane flat damage scaling at 600% of dagger damage. With physical => lighting => cold conversion, you get 600% increased damage from the Nebulis.
This build was designed to be defensive and succeeds. I can stand next to a T16 6k wisp Stygian Spire and just blast the demons as they surround me. We get 90% max element resists with a lot of help from charms. We get 93% of physical damage taken converted into elemental damage. Petrified Blood greatly amplifies the effectiveness of Defiance of Destiny, and Master Surgeons adds ~1400 life regen. We add Vitality to sustain RF and add in some leech for extra recovery.
Master Alchemist + "Reuse at the end of this flask's effect" allows for constant flask uptime (I sometimes need to manually retrigger the Silver flask, but that one is purely offensive.)
Super happy with discovering this combination. It can be set up for cheap since all of the uniques are common and gets online quickly once you get your max resistances ~85%. The poorly rolled versions of many of the jewels are also cheap.
Open to suggestions! Right now, I'm trying to figure out how to get crit immunity and more AoE.
