Is There Any Other Uses Of Dodegar's Ultimate Weapon Other Than Selling It?

At the end of the quest Dodegar told you to keep the dagger with you during your adventure.

Selling it, was just too easy. Easier than selling Caissop's Master Piece(The quest npc is at the swamp, while you need to sell it at cinfras's underground, meanwhile you can sell the ultimate weapon in a village near the quest npc) which is lower level quest reward which was supposed to be easier to sell than Dodegar's Ultimate Weapon.

So I think there might be some other uses from Dodegar's Ultimate Weapon

 

No, I'm pretty sure all you can do it sell it. It's all a joke, really. The weapon's useless, it does like 1 damage. But in order to make all of that grinding worth it, you can sell it to rake in some cash, I think it has one of the highest emerald rewards of any quest if you count the money you get from selling it as part of your "reward"
