Avascular Mass

You spawn three blood motes and hurl them at targets within range. Each target must make a Constitution saving throw. A target takes 8d8 necrotic damage, as its blood vessels violently purge blood through its skin, or half an much and no purging on a successful one.

The purged blood pools under the target, in a 15-foot-radius puddle. A creature that start its turn over the puddle, or enter the puddle, must succeed on a Constitution saving throw, or take 4d8 necrotic damage and be restrained and incapacitated until the end of its turn.

The pools of blood disappear when the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you create one additional mote for each slot level above 5th.
