Seems I haven't got that materia in my collection, this game is going to be near-impossible. I haven't even got Comet 2 and I'm waaaay off getting it.

Tried to get Omnislash tonight and yesterday, my character (Cid) keeps dying even though he's pretty strong. Do you think I can march on with de-barrier, without Omnislash, without Comet 2, without Flare - without any decent materia besides Comet 1 and Ultima, and the bare Ice/Lightning/Fire basics, and still beat Sephiroth? I also don't have Esuna, either.

By the way, is there anywhere I can buy de-barrier and where is a good place for buying items? I have like no useful items besides Pheonix Downs, Hi-Potions, a couple of Elixers etc, no megalixers or anything like that.

This is going to be hard...
