Darkness blade

You makes the shadow's combine into a solid blade of darkness . This magical blade lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 2d8 Slashing damage on a hit and has the finesse, light, and thrown properties (range 20/60). In addition, when you use the sword to attack a target that is in dim light or darkness, you make the attack roll with advantage.

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

The spell’s damage increases by one die when you reach 5th level 2d10, 3d10 at 11th level, and 4d10 17th level.
