I'm unclear on exactly what can and can't be used in a combined attack. The rules state you can use 2 or more powers as long as they are not combat/martial maneuvers. But as far as I can tell all attacks use a combat maneuver, which is either a strike or in the "other" category under combat maneuvers in Chapter 3. Could a dragon, for example, use 2 claws and a bite as a combined attack? The Hero System Bestiary seems to imply that monsters only use multiple attack, since combined attack is never mentioned in the general monster rules (only multiple attack is mentioned). I also find it strange that you only use one attack roll in a combined attack, meaning all attacks either hit or miss. It would make much more sense to me if you rolled separately for each attack, since it seems much more realistic that some attacks could hit and some could miss. I actually assumed you roll separately for each attack when I first read the rules, but was surprised when I read the FAQ stating you only make one strike roll. I find it ironic that combined attack is a strike which is in fact a combat maneuver!
