ok i just got to elfheim/land whatever you wanna call it, and all of the walkthroughs i have read say to buy that 4000 dollar sword. i bought it and tested it out and my attack power didnt go up very much at all. after i bought it i had only 2000 gil left. so shut it off so i didnt waste my money. do i really NEED this sword? will it get better when i go to the marsh cave or something? right now (without having bought the sword) i have like 6500 gil, and all of my characters are at level 7. will i be totally screwed if i dont get this? what do you say i should do?
