Eldritch Whip

A golden whip appears in your hands. For the duration, you can use an action to make a single attack with the whip. You can use your spellcasting ability instead of Strength for the attack rolls of melee attacks using that weapon, and the weapon's damage die is a d8. The weapon is magical. The spell ends if you dismiss it, if you are disarmed or if you let go of the weapon.
