Cyric's Crown of Madness - Dominate Creature/Person

 Once per day, You may attempt to Dominate a humanoid or creature that you can see within range. It must succeed on a Wisdom DC 20 saving throw or be charmed by you for the duration. If the creature is a follower of the God Cyric, it automatically succeeds the check. The target may attempt another saving throw every minute or 10 rounds of combat at the end of its turn, after 5 minutes or 50 rounds, the creature is permanently afflicted with the spell's effects, regardless if the spell is dispelled by the caster or not.

If the Target succeeds the DC 20 Wis saving throw, it is acutely aware who charmed it, and will instantly turn hostile. The caster must then make a Wisdom Saving throw, DC equal to their ability score, in order not to suffer the backlash of the spell coming to an end. On a successful save, nothing happens. On a failure, the creature starts to give in to the madness of the crown, going insane, the effects of which are up to the DM

While the target is charmed, A jagged wrought-iron crown appears on its head, causing unbelieveable pain and madness in the target, The target cackles madly, with bright wide eyes.

On its turn, before attempting a Wisdom Saving throw if applicable, the target must attack and attempt to kill the closest creature to it, to the best of is ability. The target also will prefer to damage multiple targets at once if they have access to any AOE effects or spells (i.e. fireball, arms of hadar etc). If no other creatures than the Caster and target remain, the target will kneel before the target and state "I am the One, the All, the Face Behind the Mask, I am Everything." Before attempting one last DC 20 WIS saving thrown, regardless of time controlled, on a failure the target uses any means available to end its own life.
