Atrophy a foe into stone.
If the creature is physically broken while petrified, it suffers from similar deformities if it reverts to its original state.
If you maintain your concentration on this spell for the entire possible duration, the creature is turned to stone until the effect is removed.
You extend your hand; dark energy spirals toward the target. Their flesh begins to harden, muscles and skin transforming into solid stone. The transformation completes, leaving them as a rigid, lifeless statue under your spell's power.
