I jus gt that old key and can fight hell wyrm but he has like 9,000,000 hp nd i can only take 9999 so it'll take AGES! then theres yiazmat 50,000,000 hp thats more then 4 times dark anima from x nd you could take 99999 in that then theres omega aswell is there any point jus for 1 sword or should i jus go for tournesol?

wll i fought (nd slaughterd) hell wyrm took me half an hour nd yiazmat will be longer sooo...... has any1 done yiazmat or omega nd how lond did they take o nd hus done hell wyrm how long was that for u?

First, Yes, if you can, go for the Tornesoul.Its (somewhat) faster to get than the Wyrmhero blade and it'll help you get it anyway.

Second, The Wyrmhero blade is obtained after you dispatch the marks/bosses that you would have thought worth using it on.

It took me 12-14 minutes for Hell Wyrm...
Yiazmat took nearly an hour and omega's got 1,000,000 HP
If Yiazmat (50,000,000 HP) and Hell Wyrm (8,000,000 HP) took only nearly a hour and 14 minutes respectively, then guess how much it takes for a 1,000,000 boss.

Also, it would do much good to brush up on your spelling.
It's quite annoying to read a post full of half-words and spelling mistakes.

No, unless you're going for a perfect game. I don't see why when there's more powerful weapons out there. I don't like doing the fishing minigame either. It's way too mind numbing and stupid.

You should just go for Tournesol.
