Your character advances in power by gaining experience. You need a SET
amount of EXPERIENCE points for each LEVEL based on your creation points.
You gain EXPERIENCE by:
being part of a GROUP that kills a monster
You lose EXPERIENCE by:
fleeing from combat
recalling out of combat
being the target of certain spells
The EXPERIENCE you GET from a kill depends on several things: how many players
are in your group; your LEVEL versus the LEVEL of the monster; your alignment
versus the monster's alignment; how many of this monster have been killed
lately; and some random variation.
