Tentacle Rod

This rod ends in three rubbery tentacles. While holding the rod, you can take a Magic action to direct the tentacles to stretch outward, each one attacking a creature you can see within 15 feet of yourself. For each tentacle, make a melee attack roll with a +9 bonus. A tentacle deals 1d6 Psychic damage on a hit. If you hit the same target with all three tentacles, the target must succeed on a DC 15 Dexterity saving throw or have the Restrained condition until you have the Incapacitated condition, until you take a Bonus Action to release the target, or until the target is no longer within 15 feet of you. While Restrained in this way, the target takes 3d6 Psychic damage at the start of each of its turns. At the end of each of its turns, the target repeats the save, ending the effect on itself on a success.
