Rupture

2nd-level necromancy

Casting Time: 1 reaction, which you take in response to being grappled or swallowed whole

Range: Touch

Components: S

Duration: Instantaneous

You make a slicing motion with your finger, and you immediately break the grapple of the creature grappling you by magically entering their body and exiting them on the opposite side. The creature must make a Constitution saving throw, taking 3d12 necrotic damage on a failed save or half as much damage on a successful one.

If cast in response to being swallowed, you exit the triggering creature’s body, regardless of how much damage you deal to it, and fall prone in a space within 10 feet of the triggering creature.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d12 for each slot level above 2nd.
