Interdict Boon: Acheron's Chain

Prerequisite: 7th Level Illrigger

When you use a bonus action to place or move a seal on a Large or smaller creature, you can activate this boon (no action required). You conjure infernal chains to grasp the target, forcing them to make a Strength saving throw. On a failed save, you can either pull the creature 10 feet toward you or cause them to be grappled until the end of your next turn (escape DC equal to your interdict save DC).
