Prepare to be randomly killed, a lot. And unfortunately deaths are quite severe. The amount of experience that is lost normally translates into about 2 - 8+ hours of play time depending on your class, level and experience. Additionally you can expect to lose spells upon death for certain classes.

It's a shame that a fair amount of the playerbase live to do nothing but pk and have little, to no, qualms about who is their target. The immortals have a strict hands off policy except for extreme cases.

Bottom line: If you're thinking about learning to play this mud, unless you can get in right after a player wipe (roughly every 2 years) when every body is on equal footing, it's probably not worth your time.
