Crown of Despair

As an action, one creature you can see within 60 feet of you must make a Charisma saving throw. On a failed save, it takes 1d8 Psychic damage per psi point spent, and it can't take reactions until the start of its next turn. On a successful save, it takes half as much damage.

If you spend 1 minute conversing with a creature, you can attempt to seed it with overwhelming ennui. At the end of the minute, you can use an action to force the creature to make a Wisdom saving throw. The save automatically succeeds if the target is immune to being Charmed. On a failed save, it sits and is Incapacitated until your Concentration ends. This effect immediately ends if the target or any ally it can see is attacked or takes damage. On a successful save, the creature is unaffected and has no inkling of your attempt to bend its will.

As an action, you force one creature you can see within 60 feet of you to make a Charisma saving throw. On a failed save, it takes 3d6 Psychic damage, and its speed is reduced to 0 until the end of its next turn. On a successful save, it takes half as much damage. You can increase the damage by 3d6 per additional psi point spent on it.

As an action, you choose one creature you can see within 60 feet of you. It must succeed on a Charisma saving throw, or it is Incapacitated and has a speed of 0 until your Concentration ends. It can repeat this saving throw at the end of each of its turns, ending the effect on itself on a success.
