Most UseLESS Spell

[Martyr]

Harm spells are badass!
I mean, with the amount of undead in that game, that spell is a must and a lifesaver when you have a White mage in the party.

The most useless spell is probably Lock from FF1. Mostly because it was a bug in itself and did absolutely nothing.

Otherwise, I think that most of the spells had a purpose which I have used successfully over the course of the games. I think that people who limit their spell selection aren't accessing the fullness of the game and, therefore, may as well not use magic.

The list spells are some very useful spells, however,

I think that the only one I can safely vote for, though, is poison. (Not to be confused with BIO)
Poison just never seems to do enough damage. It never saves or helps me, and, of course, Bio has the same effect with the chance of poisoning anyway, and is better all around.

Then, maybe I'd vote Slow. Slow just doesn't seem to work sometimes, and, even if it does, there always seem to be more fitting spells for the occasion than Slow. (Like Fast/Haste)

Confuse is also a difficult spell.

But none are really at all useless, IMO.

Edit: Wow. Lotta Harm Haters. Can't figure that out at all. No wonder so many people think that FF1 is hard.
