Level

Level--any of several different game factors that are variable in
  degree, especially: 1. guild level, a measure of the character's power,
  starting at the 1st level as a beginning new member and rising through
the
  accumulation of experience points to 20th level. At each level
  attained, the character receives new powers. 2. spell level, a measure of
  the power of a magical spell. A magic-using character can use only those
  spells for which his guild level qualifies him. 3. adventurer level, a 
  measure of the character's overall power across all guilds starting at
the
  1st level as a beginning adventurer and rising through the accumulation
  of experience points to 100th level. At each level attained, the
character
  is able to accumulate more guild levels and join more guilds.
