Animus' Bone Whip

You summon a long magical whip in your hand. This magic whip lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 2d6 slashing damage plus 2d6 necrotic damage on a hit and has the finesse and reach properties. In addition, when you hit a creature with this weapon it cannot regain hit points until the start of your next turn.

If you drop the weapon, it dissipates at the end of the turn. Thereafter, while the spell persists, you can use a bonus action to cause the whip to reappear in your hand.
