^^PsM stands for Princess of Moonebrooke, and and PC stands for Prince of Cannock.

Interesting notes on Spells:

  • Chance uses less MP at sea than on land.  If used on Malroth, he remains unaffected, and his health is fully replenished.
  • Be extremely cautious when using Sacrifice, as it is only learned by the Prince of Cannock, and he is also the only character that learns Revive.  It does not work on Malroth.
  • Although it usually lasts long enough, do not put too much faith into Stepguard, for it does eventually run out.
  • Even though Stopspell misses frequently, it will almost always work on any enemy.
