ok, the fiends u have to beat at the end of the 4 caverns (fire, earth, wind, & water) are hard. so an easy way to beat Lich is to have u're white mahe cast Diara on him. he is a skeleton so it will do between 100-150 damage every time (depending on u're level). Also have u're black mage cast Haste on u're strongest Warrior or Monk or whoever u're strongest physical attack person is. so there u go and enjoy.
