You choose the demon's type, which must be one of challenge rating 5 or lower, such as a **barlgura** or a **shadow demon**. The demon appears in an unoccupied space you can see within range, and the demon disappears when it drops to 0 hit points or when the spell ends. Roll initiative for the demon, which has its own turns. When you summon it and on each of your turns thereafter, you can issue a verbal command to it (no action required). If you issue no command, it spends its turn attacking any creature near it. At the end of each of the demon's turns, it makes a Charisma saving throw. The demon has disadvantage on this saving throw if you say its true name. On a failed save, the demon continues to obey you. On a successful save, your control of the demon ends and the demon spends its turns attacking the nearest non-demons. --- ## At Higher Levels When you cast this spell using a spell slot of 5th level or higher, the challenge rating increases by 1 for each slot level above 4th.
