Specialist Smith: “I hear that we are hunting down a Bhaalspawn?” Private Johnson: “Yeah. Apparently he’s got five friends and they destroyed Saradush.” Specialist Smith: “Just six of them? I was there last year! Damn, that city was big.” Private Johnson: “Good thing we got these spears! Supply says they are magic.”
I mean...they’re following orders. They can’t choose whether or not to fight you, they’re in the army. Even if the general won’t hear you out, I feel bad for killing his men. I usually just invis out of there.
(1) Temple of the Forgotten God would have the option of working with the priests there. Earning their trust and even getting them to help Attack dragon’s eye
(2) Dragon’s Eye would have RP opportunities with the prisoners. Both villagers, priestess and adventurers. Make the fake pacifists a more interesting investigation session
(3) Severed Hand would have elven ghosts on the lower levels. Make the lower levels battle grounds, where orcs and elves continue to fight to the death. Make PCs earn the right to advance by joining, and winning, in the never ending ghostly battles. Also fill the upper levels with more intelligent undead.
(4) Dorn’s Deep is harder. But you do have the cranky mage, the Dwarven ghost, and all the slaves. Work with all 3 to make it more of a RP experience.
