Djinnstrike

You tap into the dark power of Al-Ghaib to utter twisted words that spread madness. You choose a creature within range. They must succeed on a Charisma saving throw against your spell save DC. On a failed save they will get one of the following effects, and they will take 3d6 psychic damage. You choose one of the effects below:

• The target will lose the ability to speak for 1 minute. When it tries to talk, it will utter the names of the great djinn lords.
• The target's speed is reduced to 0 until the end of your next turn.
• The target cannot use reactions.
• The target will have disadvantage on all its ability checks for 1 hour.

On a success, they only take half damage and suffer no other ill effects.
