Splitting Steel Champion vs 100%Deli, Feared, Uber Bosses | POE 3.21 Crucible

Why does this build deal so much damage? ------------------------------------------------------ Splitting steel projectiles split into 7(5+2) projectiles(+2 comes from beltimber sword). Normally those projectiles cannot hit the boss. Once you annoint "Vengeant Cascade" to your amulet, they actually return and shotgun the boss. Character himself throws 7 projectiles, i guess saviour clones shoot 5 but maybe they also get benefit from beltimber i don't know. What can you do with this build? ----------------------------------------- This build is capable of doing anything in the game. I didn't have time to try simulacrum yet, but it should be doable. Character is already stun and ailment immune. Perfect uber boss killer, decent mapper( you may try chain support maybe?). I managed to clear 90%pack size 100% deli T16 Crimson temple without dying.
