Yep. He's there as a kind of joke. I don't know in how far this function can be abused. I can't remember whether it affects prayer cooldown or not.
EDIT: It's even more powerful than I remember. It makes you forget the gods, but the gods don't forget you... O.o ...maybe I should have included that as a clue. (sorry for the rhyming)
And if you happen to come accross any bugs or think of any improvements in CLIVAN, then don't hesitate to post those either. It will help me understand the nature of possible as-yet-unknown bugs I introduced there.
Holy crap man, there are lumps of human flesh on the ground! What did you do?
I guess if you find a wand of resurrection in UT you can go back for an easy belt, because when Sumo gets resurrected then he has really low HP.
Has anyone ever tried killing Huang Ming Pong with banana peels and then resurrecting him with a wand to beat him in the wrestling match?
Also, I think it is impossible to slip on a banana peel in wizard mode.
I suppose the temperatures could work like illumination is calculated in the levels, except across temperatures from -127 to +127 along one dimension (instead of RGB). So then we'd need a temperature map. Then items could have their own localized temperature and so you could have a flaming sword keeping you warm.
