Tentacled

You can grow a pair of retractable, prehensile tentacles from your body, which grant you the following benefits:

• Your tentacles can manipulate or hold items as well as your original arms can, and as such you can interact with two more objects than usual on your turn without needing to use the Use an Object action.
• You can attack with a tentacle as a bonus action melee weapon attack you are proficient with. Tentacles have the finesse and reach properties, and do 1d6 points of bludgeoning damage on a hit. When you hit a creature with a tentacle on your turn, you can use a bonus action to attempt to grapple the target. You may use a tentacle to grapple a creature of a size no larger than yours, or you may use two tentacles to grapple a creature up to one size larger than yours.
