What I do know, however, is in the case where the mob has to use a power to blow themselves up (as opposed to Skiffs, for example, who just sort of explode), you can stop the power entirely with EF. The power that Mages/Embalmed/whatever use to blow themselves up is interruptable, and EF will continuously interrupt everything that's inside it, so they can't blow up at all.

I remember hearing once that either EF or RI will also stop Vaz Morts from rezzing, and Tsoo sorcerers from teleporting. The first seems true, but the second's not. Not interruptible, I s'pose.
I've never seen a full list of interruptibles it stops, though.
