Sonar Blast
Your drone houses a devastating sound cannon. Once per hour, the drone can activate the sonic blast as a standard action, dealing sonic damage to all creatures and objects in a 30-foot cone; affected targets can halve the damage with a successful Fortitude saving throw (DC = 10 + 1/2 your mechanic level + your Intelligence modifier). The blast deals 1d10 damage for every two mechanic levels you have.
