Electromagnetic Scrambler

You emit an electromagnetic pulse, potentially shutting down all ships besides your own within 1200 feet. Ships within range must succeed on a Wisdom (DC = 8 + prof. bonus + ship's charisma modifier) or become disabled up to a minute or until the power ends. Each time the target takes damage, it makes a new Wisdom saving throw against the power. If the saving throw succeeds, the power ends. The effects of this feature last until the beginning of your next turn unless the crewmember uses a bonus action to maintain it. This feature can be used a number of times equal to your ship's tier (a minimum of once). All expended uses are regained when the ship recharges.
