Infernal Challenge (TP)

You offer a creature a compelling challenge. If you have no allies within 5 feet of you, choose one creature within range who can see and hear you. They must succeed on a Charisma saving throw or answer your challenge and fight you. For the duration, you gain a +2 bonus to AC, the target has disadvantage on attack rolls against creatures other than you, and the first time the target tries to move away from you on a turn, they must succeed on a Charisma saving throw or their speed becomes 0 until the start of their next turn. This spell ends if you end your turn more than 30 feet away from the target.
