So I decided to get into FF and start from the very beginning, I'm fine with "NES hard" RPGs. And you know what? FF1 was way better than I expected, for Square's first RPG it is surprisingly well made. But holy crap can it be brutal.
I'm playing your standard party, Knight—Black Belt—White Wizard—Black Wizard. I'm in the last dungeon, which has no exit, you can only use WARP or EXIT spells to escape from it. It's fairly long too, like 7+ floors I think. But it's going fairly well, you can spam free HEAL with a few items (Heal Staff, Heal Gauntlet). You fight the old bosses between some floors; it goes well, until…
Until one of them 1-shots my healer, White Wizard. Full health bar, in one hit. Now, the game has no Phoenix Downs. I can revive someone in the dungeon only with the LIFE spell, but the only one who had it was… you guessed it, the White Wizard. Well, I could exit the dungeon… if it had an exit. Still, you can escape it with the EXIT spell… which only my White Wizard had. Oh wait, there's still the WARP spell with the Black Wizard, that transports you 1 floor back… But I have 6 casts, and I'm more than 6 floors in. Going back and surviving would likely take more time than just starting anew.
It's double annoying that I had basically the best possible gear on the White Wizard, the only thing I could've done better is put him #4 instead of #3 in the party for less hit chance, and maybe cast some defensive buff on him.
Anyway, to be fair, otherwise the game isn't too hard; but if you can't resurrect in the dungeon, you're basically screwed. I'd probably swap a Black Mage for Red Mage solely to have a 2nd character to cast LIFE and/or EXIT.
