Tentacle Whip

1d4 slashing + 1d6 psychic
Attack rolls made against aberrations with this
weapon have disadvantage. When you roll a 20 on
a d20 for an attack roll with this weapon, the
target is stunned until the end of its next turn. As
a bonus action you can both unsheathe or sheathe
the whip from your arm.
You're not alone anymore.
