Human-powered flight is not for your average joe off the street, it requires a substantial training regimen and a baseline pilot who's already quite strong and enduring. (No particularly high agility or coordination is required, because the machinery handles that.)
This may be true, but only barely. Also see above about the extensive training that I already assumed.a strength of 20 is superhuman. we are talking about a level of strength that isn't even possible in the real world without steroids, extensive training, or both.
Basically, Str 20 is great and all, but "just slightly superhuman" is nowhere near enough to pull off a stunt like this — you need "extremely massively mega-super-human" (i.e., 30+ Str) to have a chance at it.
Dragons have a) far higher Str scores than humans, b) the afore-mentioned big wings, which are at least reasonably aerodynamic, and c) are inherently magical creatures, just like the undead I alluded to. So whether their flight is natural or Ex is undecidable; I prefer to assume it's Ex (i.e., making use of minor implicit magic that doesn't go away in an AMF, in order to bend or break physics).@dragon flight. nope. their flight is a natural ability. no magic involved, just big muscles and big wings. and they most certainly are not shaped for flight.
Sure, so? That's how they're supposed to work. I don't see any particular inconsistency here. Troll regeneration does not break my suspension of disbelief (possibly because I have nothing to compare it to), but flying by swinging an axe over my head just does.@plausibility. it's exactly as plausible as anything else in this game. no one complains when trolls regenerate their head and all their limbs within a few minutes, get them cut off again, and repeat the process.
Unless, of course, you're talking about Paul Bunyan, who I could certainly imagine pulling this off, and who has an absurdly high Str score (50, 60, 70?) and is in epic levels.
While this is usually true, you have to assume that some enemies will be just that mean, because it is a valid option. (Rare, because it's not usually worth the effort, but if the enemy is flying and wants to stop the whirlybirder, it might be considered worthwhile.)@sunder a good DM won't remind the players about how to destroy other players' gear, nor will they go around looking for ways to screw their players.
