Chains of the Jester

The user summons ghostly chains from their arms that wrap around the target, fusing into their form. The target must make a dexterity of saving throw of the user's dex modifier+10. If they succeed they break the chains and the spell ends. If they succeed the target is considered grappled. If they move they take the users level+d4 of damage. (For example, a level 5 user would roll 5d4). The user may make a dexterity throw as an action each turn to break free from the chains.
