Steps to reproduce

Cast a physical BLU spell vs. an elemental, or Jailer of Fortitude when its form does not match the damage type of the spell. And cast a physical BLU spell vs. a mob with Invincible active.

Expected behavior

Physical spells should respect slash/pierce/blunt/h2h modifiers. Elementals have 0.25 for those four across the board. Slashing type spells should not do damage to Jailer of Fortitude in a form that is immune to slashing damage, etc.

DMGPHYS and other modifiers that alter physical damage should affect physical BLU spells.
