Shock Wave
Whenever your drone is reduced to fewer than 10 HP, it immediately shuts down and unleashes a shock wave of electricity as a reaction (even if it is deactivated or destroyed by the attack). This deals 1d6 electricity damage per level to every creature within 10 feet (except the drone). An affected creature can attempt a Reflex save to take half damage (DC = 10 + half your mechanic level + your Intelligence modifier).
