Crown of Kozah

When you cast this spell, a crown of lightning appears on your head. For the duration, gain the following benefits:

• Immunity to lightning and thunder damage.
• As a bonus action, teleport to any create within 120 feet that you have dealt lightning damage to during the spell.
• Any storm under your command may not be controlled by another being. 

At the start of your turn, the crown lashes out. The strike deals 1d8 lightning damage to a random target. The crown will attack the same target until they leave its range or die. If this happens, the crown will pick a new target at random.
