Claw of Ahbdukarr (Patreon)

Weapon (sickle), very rare (requires attunement)

A discarded nail of eldritch origin fashioned into a curved blade. An otherworldly tether still connects it to its original owner. This weapon deals an additional 1d6 psychic damage to creatures with an Intelligence score of 4 or higher. While wielding this weapon, it deals its weapon damage to any creature you successfully grapple (you don't add your ability modifier to the damage).

Spacial Distortion. You can split reality to travel through space, just as the nail's owner can. You can cast Misty Step at will.

Tether of the Howling Void. Once on each of your turns, when you deal damage to a creature with this weapon you can choose to teleport along with the creature you hit as long as that creature is no more than one size larger than you. You and the creature are teleported to a random unoccupied space within 60 feet of you on a surface or in a liquid that can support both creatures. The creature that moved with you must make a DC 17 Intelligence saving throw. If the creature is grappled by you it makes its save at disadvantage. On a failure it takes 2d6 psychic damage and must roll on the Short Term Madness Table. If it fails by 5 or more, it rolls on the Long Term Madness Table instead. If the damage would kill the creature its body is hurled into the endless abyss of the Howling Void, an infinite plane of nothingness beyond the stars.

Curse. This sickle is cursed, and becoming attuned to it extends the curse to you. As long as you remain cursed, you are unwilling to part with the sickle, keeping it within reach at all times. Whenever you use a property of this weapon, you must make a DC 10 Intelligence saving throw. On a failure you must roll on the Short Term Madness Table. If you fail by 5 or more, roll on the Long Term Madness Table instead. Each time you roll beyond the first the DC increases by 2. Each time you finish a long rest, the DC is reduced by 1 until it returns to 10.

Beyond our world, within the Howling Void, Ahbdukarr reaches out with endless crooked limbs. When mere mortals look too deep into the abyss, it plucks them from our world like petals from a flower. The agents of Ahbdukarr cultivate its collection further, tearing the fabric of our world to send fresh blossoms to their eternal master. Its garden grows ever larger...
