You call forth a minor celestial archon. It manifests in an unoccupied space that you can see within range. It takes the form of the archon spirit stat block. When you cast the spell, choose Hound, Lantern, or Trumpet. The creature resembles the Archon of your choice, which determines certain traits in its stat block. The creature disappears when it drops to 0 hit points or when the spell ends.
The creature is allied to you and your companions. In combat, the creature shares your initiative count, but it takes its turn immediately after yours. It obeys your verbal commands (no action required by you). if you don't issue any, it takes the Dodge action and uses its move to avoid danger.
