You call forth an undead spirit. It manifests in an unoccupied space that you can see within range. This corporeal form uses the Undead Spirit stat block. When you cast the spell, choose the creature's form: Ghostly, Putrid, or Skeletal. The creature physically resembles an undead creature with the chosen form, which determines some of the traits in its stat block. The creature disappears when it drops to 0 hit points or when the spell ends.

The creature is an ally to you and your companions. In combat, the creature shares your initiative count, but it takes its turn immediately after yours. It obeys verbal commands that you issue to it (no action required by you). If you don't issue any, it takes the Dodge action and uses its move to avoid danger.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, use the higher level wherever the spell's level appears in the stat block.
