Thanks for tagging me,

Hello, Hexagon Hero! Welcome to Final Fantasy Zz! Congratulations on sticking it out this far! Which version are you playing? I hope it's the most recent version--2.3. A lot of websites list version 1.51 as the final version, which is most unfortunate.
Regarding Ice Cave strategies, I would tend to do the following:
1. Go into the Volcano first to get the two ProRings.
2. On the bottom floor of the Ice Cave (B3), I would give one ProRing to my WM (if I have one) and the other ProRing to my lead character. If I don't have a WM (who can cast LIFE), then I would give the two ProRings to the characters in the top two positions. This way I'd have the best possible protection in case there's a group of Mages/Dark Elves.
3. For the Evil Eye fight, the WM should cast XDTH, of course. But if you don't have this spell, then the ProRings should be equipped by the characters whose max HP is below 300 or is easy to fall below 300. This is a tricky fight because of the Ghosts.
4. If you have the BM, you can WARP out fairly easily after getting the Floater. You'd still have to survive one runnable spiked square and hope that the encounters on B1 are not cruel to you.
It is possible to use WARP to take a "shortcut" to the Floater without dealing with all the crazy random encounters in there. The tradeoff is that you'll have to suffer through a bunch of miserable spiked squares to do so. This is certainly doable, but it's definitely miserable.
Regarding the Titan's Tunnel, it was purposely designed to drain your resources since you'll have to travel through it twice. There is a House in Sarda's Cave to restore your magic. But if you are a bit too liberal with your potion consumption, you could really be in trouble.
The Sea Shrine is probably my favorite dungeon in FFZz. I had a lot of fun redesigning that place. But be careful! The monsters in there are dreadful. It may help if you make a map. If you'd like to venture into the Waterfall first, you certainly could. But that's not an easy errand either.
At this point, you should not worry so much about your levels. You WILL be at Level 50 when you beat the game. I've had a few teams that were in the upper 40s when they made it to the TOFR, but that's rare.
Also, your inventory is more important than your levels. You need to start thinking carefully about what weapons and armor you want to keep and what you're willing to throw away. This will result in some tough decisions about some of the enchanted items you've been carrying around with you. It can be hard to say goodbye, but I made sure to put a few duplicate items in some random chests in case a player has buyer's remorse.
Thanks again for playing Final Fantasy Zz. Good luck! You'll need it!
