concentration, 1 hour/mana

As two actions, a creature that you can touch or see within 10 meters has its blood vessels violently purged through its skin. The creature must make a Fortitude saving throw. If the creature has no blood in its body, the spell has no effect on it.

On a failure, it takes 2d8 necrotic damage.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

If the creature takes damage, the avascular mass erupts in a sphere centered on the target. The avascular mass is difficult terrain and lightly obscures its area.

If the avascular mass isn’t anchored between two solid masses (such as walls or trees) or layered across a floor, wall, or ceiling, it collapses on itself, and the spell ends at the start of your next turn. The mass layered over a flat surface has a depth of 1 meter.

A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Reflex saving throw.

On a failure, a creature is restrained as long as it remains in the avascular mass or until it breaks free.

A creature restrained by the avascular mass, or one that can touch the creature, can use an action to make a Brawn or Nimbleness check (its choice) against your spell save Difficulty. If it succeeds, it is no longer restrained.

Any 1-meter cube of avascular mass that takes more than 10 radiant damage on a single turn disintegrates. When the spell ends, the blood vessel mass becomes a small layer of limp, decaying tissue.


You can increase the damage by 2d8 for each additional mana expended.
