[quote name='nickerous']SNES. If you have access to a Game Genie, you can get out of the level grinding. At least, I had to level grind towards the end of the game.[/QUOTE]
Back when the game just came out, my friend showed me you can beat the game WITHOUT getting any characters in the second half... in other words, he used only 3 characters.
There's a magic combo that works on almost all the enemies and a lot of bosses in the game (even Atma)...
Vanish + Doom/X-Zone (I can't remember if its doom, x, or both)
For whatever reason, vanish makes those enemies 100% vulnerable to the second spell.
Oh, he also used a two sword combo (Usually on Locke), one was Valiant and the other was Ultima. At least I think those were the swords, one is supposed to increase damage if you're close to full health, the other increases damage as you're low on health. So, no matter what, you do a ton of damage. Of course, you needed Genji Gloves to equip two swords at a time.
