I once proposed the idea of beating FFI with one character at level 1. Here's how:
Fight Boss with Level 1 character and other 3 characters dead. Don't save.
Reload, kill Level 1 character, kill boss with other 3 characters. Save.
Kill other 3 characters, revive Level 1 Character. Repeat.
so, you kill the boss at level 1, and to prevent leveling you just don't save.
Now, which character would be best?
I say either White or Red Mage. White has Blink, Red has Sleep, 2 very useful spells. White has more Magic power, but Red gets better armor though.
Now how about how possible it would be?
I've taken it to Pravoka with a Red Mage. At level 1, Garland was attack and heal. I got the longsword and fought the pirates. I used Sleep and hoped for the best.
From there, the piscodemons were next. To beat them, I needed two or three Thundara items from the ship game, and I needed to dodge their attacks. I never got that far.
...discuss. Where do you think it would stop? Who would make it farther (Red or White)? What strategies could be used to get past certain bosses?
