Tap a somewhat serious-looking Lafi on the shoulder.

Summary Oh, yes! Great work! Say..
there's something odd that I noticed while watching you fight.
Do you remember the final weapon, Amarillos?
Well it just... bolted.
You went to town on it! Smashing it to smithereens!
Could you not feel it shaking madly in its final moments?
And even at its wit's end, it fled like a bat out of hell!
There is no other weapon like it in the world.
Weapons shouldn't be capable of fearing death.
Look here... they're generally all designed like this...
Huh.. wait... I feel an unusual pulse here.
Oh see! Just now! It's as if it's using all its might to take a final breath.
Although it's buried within in a labyrinth of ancient characters...
I shall get to the bottom of this mystery...no matter what it takes!

Quest Text That's strange...it makes no sense.
Weapons cannot feel fear of death.
