Most of spells introduced in the original realese of Dragon Quest II had a different translation, so in later re-releases, they would retroactively have their name changed to reflect the modern naming scheme. In late re-releases the MP cost as well as the required level was also rebalanced. The prince of Midenhall is the only member of the party that cannot learn any spell.
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.
