As a Bonus Action, you can expend 3 Charge Points to create a 1-foot diameter ball of electrified plasma in an unoccupied space within 5 feet of you. The ball lasts for 1 minute or until you use this feature again or dismiss it (no action required).
The ball emanates an electric field in a 5-foot Emanation. When a creature enters the Emanation for the first time on a turn or begins its turn there, you can choose for metallic weapons it is carrying to gain an electric charge until the end of the creature's turn. Whenever a creature deals damage with a charged weapon, it deals an extra 1d6 Lightning damage.
At the start of each of your turns, the ball moves up to 15 feet in a direction you choose.
