JADE gods
JADE would be really cool if you had more interaction with the various gods. Such as going to their lair (or palace) and getting quests to slay a troublesome monster (or a rival god). And they could have a giant heap of treasure like the water dragon's lair, including a special artifact used by that god. Also a few monsters (like solars and holy slayers and such) for some flavor elements (and get ticked if you attack their god)
Of course, you'd have to be crowned (or invited) by that god to go to it (and maybe a certain level) and if you change alignment to a god's you killed, he can't help you or you sacrifice to him.
So, what you ya'll think?
When in darkness, you can always see the light (unless you're in ADOM)
Most successful combos for me: Grey elf wizards, trollish healers, dark elf beast-fighters, Gnomey monks, and any race barbarians.
