Ok, I just dug out my OST for DQ9, and here are some of the highlights about beating Corvus's second form:
1. He puts members of your party to sleep/paralyzes them frequently, so be prepared for those.
2. He casts Disruptive Wave often (even if you have no buffs), so buffing up your characters is fairly useless.
3. Have a Priest or Sage cast Multiheal just about every round, even if you feel you may be partially wasting it.
4. The OST recommends not using Multiheal after Corvus restores his HP unless they're above 190 HP
5. Have other characters restore your healer's MP, not have them restore their own.
That's about all the OST has in it. Good luck!
So all of the content is still available online? And of course they've quit adding new content right?
