Fighter/15th/Brute

Brutal Finish

Upon reaching 15th level, your attacks become so devastating they rend even the afterlife. Whenever you reduce a creature to 0 heart points with a weapon attack or unarmed strike, its body is destroyed to the point that in effect no corpse is left behind. The creature cannot be resurrected by a spell of fewer than 13-points (lower than 9th level), nor any other effect that doesn't first create a new body for the creature.

Barrier Breaker

Starting at 15th level, your attacks can smash or pierce through barriers both mundane and magical. You ignore any damage resistance (but not damage immunity) against your weapon attacks and unarmed strikes.
