Wreathed Weapon

Draw energy from your tempestuous soul and imbue your currently held weapon with the storm. Lightning crackles along your weapon and licks at your forearm.

Until the spell ends your imbued weapon uses your charisma modifier to make attack and damage rolls. Weapon attacks made with it deal an additional 1d6 lightning or thunder damage, chosen each round, your weapon is considered magical for the duration of the spell. The spell automatically ends if the weapon is dropped or knocked out of your hand while you are conscious, if the spell is ended this way you take 1d4 lightning damage.

 At Higher Levels. When you cast this spell at 4th level or higher, its damage is increased by 1d6 for every 2 spell slots above the 3rd.
