to a point i never ran into wizards, but the optional dunegons were hard plus going though it 4 times to defeat them all was whack but you do get better weapons and armor by doing it

The Chapels are the church-like places where you can revive your KO'ed party members without aid of a Phoenix Down or Life magic.

I actually found the Ice Cave really easy. By that time I'm usually way over powerd by accident and just slash my way through. Marsh Cave however is longish, and has enemies who poison your characters, which is a bum that early in the game and run out of MP for Poisona and/or Antidotes.

Didn't have a problem. I had 99 Antidotes and Poisona lol. In the NES version, I can't remember. I was 4 when I played that game. I have a emulator, gotta start it again. Is it that much harder then the GBA version?

Yes. I find the NES version of the game more or less unplayable, especially after being so much used to the GBA version. Well not so much hard, but annoying and tedious, can never bring myself to get much futher than Garland haha.

*nope!actually the only problem in this dungeon at the point of the game was its distance from the town,you pack a lot of potions and antidotes to stay alive here.

*the most annoying dungeon for me was the snow cave,where monsters called "dark Wizard" can be encountered.these monsters cast a spell called "poison" which doesnt inflict the status poison but instanly kill a party member or worse the whole party!
