The Jade Fang

The Jade Fang +3
The Dagger can be found while doing a personal quest for a certain crypt loving thief.

Item description
"This dagger is made entirely from a single cut of jade and has an edge suitable for splitting hairs. A complex ornamental design can be seen on either side, although their historical or cultural significance has long since been forgotten.

The Jade Fang was the weapon of choice for famed Shou Lung thief Niu Weidan, who would use the dagger to immobilize his opponents before draining them of their life force to reinforce his own. Cornered countless times, Niu was always successful in using this dagger to escape. In the end, it wasn't an enemy or vengeful victim that felled Niu, but rather old age. The blade was passed down through his family as an heirloom and did not see use as a combat weapon from that point onward."
