It seems to me that this goes back to invoke for effect. You use your power 8 rote to throw a car on someone and do "x" damage, adjudicated however you wish (either the damage is part of the spell - our wizard has air magic with a "throw stuff" spell. It's a power 7 Rote where he throws debris at baddies -or by saying it's a power 8 Might spell that can lift a car and the car does "x" damage); in either case, from what I've been hearing from people, is that you have to compel "there's a car on you and you can't get up" or "after you fall through the bridge you get hit by a passing car". I'm not sure you can just automatically do more stuff. But I got your point: a maneuver can kill someone when the power is that high enough.
I guess it kind of answers my invoke for effect question. While there is no official aspect on the target, I could just say "he got hit by a flying car, I'd like to invoke that he's pinned under it". Then it's up to the GM to decide what happens.
Another thing I've been seeing from people is that Power 8 rotes are awesomely powerful (I've notice that somewhat in our game that the wizard takes things out quickly). It seems well within the rules to have that kind of power...our skills are capped at superb and he gets his foci + whatever refinery...Is this kind of power unusual at this lvl? (10 refresh). When I start to GM should I be concerned?
Random Thought : people keep mentionning blinding people. Do you keep compelling the blindess? Are there rules around being blind and how it affects dodge. There must be a thread on this topic...
EDIT: here's one.
http://www.jimbutcheronline.com/bb/index.php/topic,19694.0.html Although it doesn't mention things like what Belial66 was saying,
" If it is a block against perception (offensive veil), you could really blind your opponent so they can't see you to target you and then get up to them and shoot them in the back for the next 2 exchanges - they'll roll mediocre defense since they won't be able to see the attack to dodge... Even big enemies rarely have Alertness high enough to pierce a 7-shift veil and then the entire group can hit them when they can't see to dodge for double the normal effect of their attacks."
I assume these are all compels as well?
