It's always been an unwritten rule (and since I said "unwritten", read that as-- "IMO" and let's not sidetrack on a debate about this aspect of the post) that NPC's don't use Edge. Or goons, anyway. It just slows down the game, if nothing else. Certain key NPC's are obvious exceptions.
However, what about Spirits and summoning/binding? The SR4 rules give out powerful Edge to Spirits like it's candy-- a Force 8 Spirit will have Edge 8 just for being him/her. Does it use edge to resist summoning? Surely it would rather be on it's home plane. What about binding? If so, what about if I have the quality that has that spirit type like me? Then would it?
Recently a GM at GenCon had the spirit use Edge to reroll its failures b/c I used edge to reroll my failures-- I was stunned, but didn't see this as totally off base. I personally thought I'd only have the Spirit use edge if the mage glitched.
Now on the flip side-- if someone does summon a force 6 spirit, that has easy access to Edge... does the spirit use this Edge when doing a task for the mage?
Are there any guidelines in SR4 RAW that I missed? Additioanlly, what is SRM guidelines on NPC's using Edge.
Thanks again
