Compelled obediance

You touch a creature and place an invisible mark of obedience on it. The creature must succeed on a Wisdom saving throw or be marked for the duration. If you or creatures friendly to you are fighting the target, it has advantage on the saving throw. While the target is marked, you can issue commands to it (no action required). You and the creature must share a language, and it must be able to hear your commands and understand them. You can specify a simple and general course of action, such as “Wait here,” “Open that door,” or “Kneel.” A creature cannot follow commands that would cause it to harm itself or violate its core beliefs. If the creature fails to follow your command with its next action, the mark you placed on it bursts into searing light. The creature takes 4d10 fire damage and 4d10 radiant damage, and the spell ends. At Higher Levels. When you cast this spell using a 6thlevel spell slot, the duration is concentration, up to 10 minutes. When you use a 7th-level spell slot, the duration is concentration, up to 1 hour. When you use a spell slot of 8th level or higher, the duration is concentration, up to 8 hours.
