Arcane Sword

You manifest in your hand a sword of magical force. This magic sword lasts until the spell ends. It counts as a martial melee weapon with which you are proficient. It deals 1d8 force damage on a hit and has the finesse and versatile (1d10) properties. In addition, when you use the sword to attack a target you get half the damage back as temporary hit points, which manifest as a opaque force field.

 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.

 At Higher Levels. When you cast this spell using a 3rd-, 4th- or 5th-level spell slot, the damage increases to 2d8 (2d10). When you cast it using a 6th- or higher level spell slot, the damage increases to 3d8 (3d10).
