Soloed this guy with my RDM 65. Pretty hard fight, even with stoneskin and phalanx on. Special attack was very tough for me. Good exp (38), dropped a scroll of Absorb-INT. For skill up, I think it's better Crawler's Nest ^_-
I got to go with a bunch of high levels for coffer hunting some time ago. Spotted one in the back halls and ran a check on it. It was at least IT++ at lvl 32-35. They died pretty fast with a full alliance of 55+ people though, so I never got to ask the rates from everyone else.
Errr, by kemetic, are you referring to ancient Egyptian mythology? In the time of the pharaohs, it was believed that a person's soul, or ka, left the body at death, and the person could return to life (afterlife, actually) if the ka entered a likeness of that person. This is why there are many statues of pharaohs in the pyramids and other tombs.
The ba is another name for the ka, but the ba refers more to a 'winged' spirit than a 'regular' spirit.
