Celeste The Edge of the Storm

After the magical word has been spoken a longsword made of bronze lightning booms in the palms of the wielder, The sword is named Celeste The Edge of The Storm. The blade only lasts for 15 minutes. Celeste emits a light reaching about 5ft wide.

The longsword counts as a simple melee weapon with which you are proficient. It deals 2d8 lightning damage on a hit and has the finesse, light, and thrown properties (range 20/60).

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.
