Elemental Sword

You summon primordial energy to create a sword of solidified elemental energy in your hand. When you cast the spell it takes the form of air, earth, fire, or water. This magic sword lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 3d8 cold (water), fire, force (earth), or lightning (air) on a hit and has the finesse, light, and versatile (3d10) properties.

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 sword to reappear in your hand.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage is increased by 1d8 (1d10) for every two levels above 3rd.
