Low lvl run

[Xanatos]

Well no it is possible, he will just have to know what items to obtain at what time in the game, what materia combos to put in his gear. What skills bosses use so he knows what equipment to put in that absorbs and what not, what Enemy Skills that give you the advantage on a boss. If you want to do a low lvl run, you need to have beat the game multiple times to know what to do at what moment.

I disagree with you on this one, levels exists for one simple reason and that's to raise you're stats. If you are not on high level that means you don't have enough speed, strength, luck, evasion... and no mater what kind items and materias do you posses, boss will crush you because he's multiple times stronger and faster than you. I know I had many times problems with some opponents even tho I was on a very high level and because of that I don't really see how it could be possible to beat a game with thta tactic.
