Allllright, now I get it. I’m quoting this first because this is really the source of your troubles: You’re supposed to get them as soon as possible, and should really have at least one character with all three by now. Quickenings are nigh-useless in battle other than as finishing blows and are quickly outclassed by buffing spells, but they multiply your MP. The second Quickening unlocked means X2 MP and the third is X3. That’s why you’re having MP shortages, you’re playing with 1/3 of what you should have.
Eryut Village. I made a mistake, you shouldn’t have it yet, but you’re going there right after Jahara, so it’s close
No they don’t. Vossler does something like that, but not as bad and nowhere nearly as often. You’ll know what I’m talking about once you go against one of the big Wyrm Marks. The only enemy at this point that should be able to damage you fast and bad enough to lock you in the defensive is the Gil Snapper’s Blizzaga chains once it’s frenzied… or, well, the enemies in Garamsythe, but you’re not supposed to go there yet anyway until you’re round lvl30.
The first issue is your reluctance to cast Cura. In this game, you’ll be using essentially 90% of your MP in healing, with the other 10% only used in buffs. Mostly because you have nothing else to use them on. In a boss battle, casting a healing spell every five or so enemy hits is commonplace. Fix the Quikening shortage and the rest’ll fall into place.
I don’t mean to sound patronizing, but the game’s first seriously difficult marks are the Gil Snapper and the Trickster, everything before is more of a warmup.
By the way, are you using Berserk? You’ll have Haste in a short while, but even by itself, Berserk makes boss battles much easier.
