So, The party is deep in the hall of harsh reflections, and comes across the mirror maze. inside the maze, the three dopplegangers attack! everyone's taking a bit of damage here and there, naver and Alanna have both taken moderate damage. Naver's player had a schtick - he hated using his spells, so his feats were point blank and precise shot, along with a couple of other feats. he fires his crossbow into the melee of alanna and one of the doppleganger guards. he manages to hit the cover instead (alanna) with a critical hit from his crossbow. he then proceeds to roll max damage. on it's turn, the doppleganger hits alanna for some heavy damage, dropping her into the negatives - another of the party members runs in and manages to drag her corpse away from the doppleganger. another pours a potion down her throat, stablizing her at -1. naver's player carefully counts squares, and realizes he can drop a lightning-substituted fireball into the back corner and not hit any party members.
here's where it gets tricky - the corner was in direct line of site, but there were other corners in the way, and so I told him that he had to make a ranged touch attack to hit the square. I was going for AC 12. he rolls a natural 1. I point to three spots for premature denonation, have him roll a d3. it goes off in the square that nails three party members and the doppleganger. naver was dropped to -21 hit points in one shot, alanna down to -24. the other party member makes his reflex save and had taken no damage, so he lived. the doppleganger was at 2 hit points, so it died.
