The cerberus drone should have 3 seconds(30m) before firing on the person who launched it, to allow the drone to target someone else, or to get away from it before you take grevious damage. However, you can still fire it and stay near it or just not move and still take some damage, allowing self damage synergies.
For clarification, the drone will move, but can not shoot for 3 second/30m, and only after will it target the closest person/drone
