One of the most shocking moments in the game is during the final temple when suddenly you get ambushed by a familiar face.... Lich. The elemental fiends each challenge you to a rematch in the final temple. Each one on a different floor. Lich's is the toughest of these rematches since it is impossible to prepare for it unless you have played before, plus he also is stronger with access to more powerful magic. The other three are about the same just without their weaknesses from previous fights. The walkthrough's done being written other than Warmech and the final boss. I really need to get around to launching that thread. And finishing the last two optional bosses in FF5. Anyway, here is the Lich rematch in FF1.
