@Storm:
I'd make it an opposed Spellcasting + Magic vs. Drone Body x 2. Suffered by drone when it hits a wall would be drone's Body S damage, net hits add to this damage. If the drone is thrown at another drone, then then we'd make a second opposed test Spellcasting + Magic vs. target drones Reaction. The damage would also be Thrown Drone's Body S, net hits add to this damage. I'd say you could do all this with a 1 Complex action spellcasting action.
When you levitate a drone though, your hits still need to beat the 200kg/hit threshold to lift something.
Remember each use of Accident will cost a service.
@Zach:
Remember, Jamming on the fly requires you to do an Electornic Warfare + Signal vs. a targets Electronic Warfare + Signal. So you have to identify a signal that you want to jam first, it's not like a general area jammer.
