You weave together bolts of energy to create a sword of solidified lightning in your hand. This magic sword lasts until the spell ends. It 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 the blade strikes a creature, they must make a DC 12 Constitution save or be stunned until the start of their next turn, unless already stunned. If a creature succeeds on the save, they are immune to being stunned from the blade until the start of their next turn   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.
