Keen Dragon's Wit

Keen Dragon's Wit is a weapon available in Dragon's Dogma.

Description

"An alchemick golden archistaff shaped like twin dragons. Worth a fair bit of coin, but otherwise unremarkable."

Reward from Clarus for escorting her to the northeastern Healing Spring in the quest A Pilgrim's Plight.
Sold by Mountebank at The Black Cat after completing the above quest.

In order to receive the quest A Pilgrim's Plight from Clarus, Affinity with her must be high enough to activate this quest. This quest can be available from notice board in the Union Inn upon arrival in Gran Soren even before going to the Pawn Guild.
Goldforging and enhancing Golden weapons increases their chance of inflicting Silence. The Silence debilitation is most useful against the Dark Bishop, Frostwyrms, Wights and Liches, since it renders these foes harmless. They continue to try to cast spells, unable to heal the debilitation.
Selling Golden weapons for profit early in the game is a good way to accumulate gold, prior to accessing the game's later farming areas such as the Post-Game Everfall.
Golden Weapons are the only weapons that inflict Silence; these weapons must be reinforced to at least 3* to acquire the debilitation.
