Help on DM command:
*advance [player] [level]
This will change the level of a character to a specified level. It will
also update hit points and magic points (It can lower, too.). Note that
this will also set their max level, so if you *advance someone to 30 and
then *advance them to 1, they will "relevel" all the way back to 30. Fix
this by: *set c [character] alvl [level].
example:
:*advance Terrance 5
Terrance has been raised to level 5.
