Spell Description
Using a Higher-Level Spell Slot
The creature is an ally to you and your allies. 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 action and uses its movement to avoid danger.
Use the spell slot's level for the spell's level in the stat block.
