Spell Descriptions

The spells are presented in alphabetical order.

Avascular Mass

8th-level necromancy

Casting Time: 1 action

Range: 30 feet

Components: V, S, M (a short length of rope stained with blood)

Duration: Concentration, up to 1 hour

You shoot a ray of necromantic energy from your outstretched hand, causing any living creature struck by the ray to violently purge blood vessels through its
skin. Make a ranged spell attack against the creature to disrupt its blood vessels. On a hit, the creature loses half its current hit points (rounded down) and the creature must make a successful Constitution saving throw or become stunned until the end of its next turn.

The purged blood vessels magically animate, creating a many-layered mass of magically strong, adhesive tissue that fills a 20-foot sphere centered on the original target that traps those caught in them. If the avascular mass isn’t anchored between two solid masses (such as walls or trees) or layered across a floor, wall, or ceiling, the mass collapses on itself, and the spell ends at the start of your next turn.

Each creature that starts its turn in the mass or that enters them during its turn must make a Dexterity saving throw. On a failed save, the creature is restrained as long as it remains in the mass or until it breaks free. The original target of the spell is automatically restrained. Regardless of a creature’s saving throw result, the avascular mass counts as difficult terrain when moving through it.

A creature restrained by the mass can use its action to make a Strength check against your spell save DC. If it succeeds, it is no longer restrained.

If you have at least 5 feet of avascular mass between you and a hostile creature, it provides three-quarters cover, and if you have at least 20 feet of avascular mass between you, it provides total cover.

When your concentration ends or the spell breaks, the blood vessel mass becomes a mess of limp, decaying tissue.

 

Avasculate

7th-level necromancy

Casting Time: 1 action

Range: 30 feet

skin. Make a ranged spell attack against the creature to disrupt its blood vessels. On a hit, the creature loses half its current hit points (rounded down) and the creature must make a successful Constitution saving throw or become stunned until the end of its next turn.
