Devil's Chains

You brandish the chains used in the ability’s casting and make a melee attack with them against one creature within 5 feet of you. On a hit, the target suffers 1d8+ your Stregth modifier slashing damage. If wielding the chains with two hands the chains gain the Reach property and instead do 1d10+ your Strength modifier slashing damage.

When you take the Attack action and make an attack with a chain, you can use a bonus action to initiate a grapple with the target of your successful attack.
