PoE 3.23 Affliction, 3.22 Ancestor Occultist, Physical, Spell builds

The idea is simple: Ethereal Knives with Return Projectiles and Sadism Support and Returning Proj Support for clear Blade Blast on a trigger weapon with Sacrifice Support to help with single target In theory this should feel great to clear with as you get Occu explosions and the fake-hit build feel with the fast poisons from EK while keeping long poisons on Blade Blast to still have some consistency/room to dodge mechanics. No idea about damage but it sounds cool enough for me to take it for a spin, what are your thoughts?
