Toastius

Needs: wizard with Gaze of the Adragan, priest for reliability - Agree to release the dragon, get the amulet, take it to the dragon-hunter and then tell her what the plan is. Gets you Scale-breaker, and means the dragon is friendly until you you attack it. - Send someone around the side of the dragon to initiate and bait the breath weapon; I used a max-level Eder, who managed to not die. - Do everything you can to buff your wizard's accuracy quickly; I used Devotions for the Faithful. You don't want to spend too much time on this, because you've got a lot of incoming crap. - Scale-breaker the dragon. - Attempt to petrify it with Gaze. You get three attempts at max level, and you need one to land. Might not have time to make three attempts, though! - If petrify lands, kill dragon. Then kill everything else. Otherwise reload and try again. Petrify's effects seem to be really poorly documented; get yourself petrified to see what's really going on (I don't remember exactly what it says), but it seems to basically make things explode when you breathe on them. Also works on the Sky Dragon, which is even easier with this method.
