rolling slam doesn't hit Zalmarath (Collossus boss)

you literally cannot hit him with it and it's not an accuracy problem because i have Resolute Technique.

Both of the giants (Skeletal Bone Tyrant in the center of a ring & the huge guy with a dagger/lasers) have incredibly wonky hitboxes/auto-targetting issues. Using Unarmed Strikes (can't be evaded) on them is a fool's errand, regardless of where the cursor is clicking. The same issue is present for Vaulting Impact/Tempest Bell.
