Congeal Formless Spawn

6th-level conjuration

Casting Time: 1 action

Range: 30 feet

Components: V, S, M (a vial of blood from a creature with Intelligence score 5 or higher, which the spell consumes)

Duration: Concentration, up to 1 minute

You empty the vial of blood, which immediately roils and seethes, becoming a formless spawn in an unoccupied space you can see within range. When reduced to 0 hit points, it dissolves into a thin film of revolting residue. When the spell ends, the formless spawn does not vanish but immediately leaves to seek its own mysterious goals.

The formless spawn is hostile to all creatures besides oozes and servants of Tsathoggua, to whom it is indifferent.

Roll initiative for the formless spawn, which has its own turns. The formless spawn pursues and attacks the nearest non-ooze creature obviously hostile to Tsathoggua’s servants. If none are available, it attacks other creatures to whom it is hostile while the spell lasts.

At Higher Levels. When you cast this spell using a 9th-level spell slot, you instead produce two formless spawn.
