Sphinx - Stage 4 (Guardians Fortitude)

Boons:

• Guardians Fortitude: You become immune to Psychic damage, as well as bludgeoning, piercing, and slashing damage from non-magical attacks. In addition, you cannot be charmed or frightened.

Flaw:

• Celestial Blunder: Your new native plane attempts to pull you to it, laying claim to your form. Whenever you roll a natural one on a saving throw against a spell or magical effect, you take 10d6 force damage, which cannot be reduced in any way.
