Delsaber's right arm

[Ratsmack]

Is what I have. Everyone knew this question was coming, but what do I do with it?

[Tank]

Take it to Dr. Montague on either of the two quests where he stands outside the Hunter's guild. (Dr. Osto's notes is one, I believe.) He'll change it into a weapon for you, delsaber buster. It's not the most powerful, but it is incredibly cool looking. If you find Delsaber's left arm, let me know, and I'll trade or buy it from you.
