I forget the exact name, but there are dudes in the Shin-Ra building (something like SOLDIER No. 3 or some shit like that) that have Hardedges you can steel. Those things are amazing for Cloud to have that early in the game, since you normally can't buy them until Junon.
That, and if you grind enough to level up your characters/materia in the Shin-Ra building (like I did, whoo-hoo Bio2 lol rhyme), the game is ludicrously easy also until about the Junon region.
