You call forth a shadowy spirit. It manifests in an unoccupied space that you can see within range. This corporeal form uses the Shadow Spirit stat block. When you cast the spell, choose an emotion: Fury, Despair, or Fear. The creature resembles a misshapen biped marked by the chosen emotion, which determines certain traits in its stat block. The creature determines when it drop 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 your. It obeys your verbal commands (no action required by you). If you don’t issue any, it takes the Dodge action and it uses its move to avoid danger.
