Circle of Weakness

Winning magical combat often requires exploiting weakness. You evoke a circle of floating inscriptions that creates and amplifies energy-based weaknesses on creatures inside the circle. Choose one type of damage from the following list: acid, cold, electricity, fire, force, or sonic. When you Cast the Spell and the first time you Sustain it each turn, each creature in the area must attempt a Fortitude saving throw.

Critical Success The creature is unaffected.

Success The creature gains weakness 1 to the chosen damage type for 1 round.

Failure As success, except the weakness is doubled.

Critical Failure As failure, and the creature becomes Immobilized for 1 round or until they Escape.
