You know you will find out that it is reaaaaaally not worth it in the end...

If you just get the Ragnarok, Ultima Blade, and Excalibur and you are a high level with lots o strength then you will do 9999 damage all the time. The Tourensol or Wyrmhero Blade won't do a difference if you are already doing that much damage.

Besides, the bazaar is a bitch.
