Clerics have a game they play sometimes among themselves. They see who can get the most experience points out of killing a little crab.
Clerics get a small amount of experience points from casting Bind on both players and monsters both (no more than 300 xp) So, sometimes, when Clerics are bored, they hold contests to see who can fight and bind crabs on the beach the longest, generating the most experience points.
Obviously, the low level Clerics have the advantage in that they don't hit hard, but they do have limited SP, so they have to leave the room and rest a bit. While high level Clerics can cast Bind all day, but hit hard enough to kill a crab rather fast.
The current record is held by a long forgotten, nameless Cleric (it was so long ago that Nelat, in his advancing age, forgot the name. You know, Nelat, when you get old, memory is the first thing that goes... and i'll be damned if I can remember the next thing...) And this Cleric spent four hours fighting a crab, and finally killed it, after generating 18,000 experience points. Amazing.
