Assuming no one else ever responds to this, I'm gonna make one final post, as my own "Tips For Newcomers" thing.

1. PLAY TRIPLE TRIAD. GET CARD MOD QUICK! That dragon thing at the top of Dollet Communication Tower will annihilate you if you do not.

2. DO QUEEN OF CARD SIDEQUEST AS FAST AS POSSIBLE AND GET IRVINE CARD IN FH. You have no idea how essential three Auto-Hastes will be for a lot of the boss fights. You won't need it for the final stretch but for most of Disk 2 and 3, it's a lifesaver.

3. Always have Protect and Shell up in boss fights. Always.

4. The only way to get Vit 0 in this game are: Quistis' Acid, Quistis' Bad Breath and Angelo Strike. It's a lot easier to get Vit 0 with Acid. I never used it until the final boss fights but it be nice to have. However if you're close enough to death to get Limits off in this version, you're probably dead anyway.

5. If you are having trouble with the Oilboyles, a Tri-Face is a very rare encounter in that final area of the MD Level. If you're a high enough level, as I was, you can draw Flares from it and help increase your HP a bit while getting a powerful attack spell. Tri-Face will wreck you though so you'll need to Sleep it if you want to draw 300 of them.

And...I think that's it. Requiem was a ton of fun and I hope more people will play it.
