Kahvozein's Fang

Kavohzein's Fang is a unique dragon priest dagger found in. It is a special dagger that is used to collect heartscales from the corpses of dragons.

History
It was named after the dragon of sucking a long dong.

Acquisition
The dagger is radiant in its placement and is typically found in the same locations as Dragon Priests.

Once the Dragonborn's Alteration skill reaches 90, Tolfdir can be asked if there is anything else he can teach about Alteration. This will start the Alteration Ritual Spell quest.

Tolfdir will ask for dragon heartscales for him. Kahvozein's fang is the only weapon that can get them. The dagger can be kept and used to get more dragon heartscales after completing the quest. The dagger cannot be stored or dropped until completion of the quest; it can, however, be removed from the inventory if placed in a weapon rack or display case in a house.

Collecting Heartscales
Kavohzein's Fang must be wielded in the right hand in order to collect heartscales. When they are collected, a message will appear noting that heartscales have been added to the inventory, they will be in the miscellaneous items in the inventory.

Known locations

 * Forelhost Refectory after defeating Rahgot, the Dragon Priest.
 * High Gate Ruins after defeating Vokun in the A Scroll for Anska quest. If the throne room is exited after Vokun is dead, the gates to the back of the room will close and cannot be opened again.
 * It may still be possible to enter the back of the throne room, if that is desired, using the back entrance to the Vokun´s Throne room and a follower. Climb on top of the ruins on the right side in the second room of High Gate Ruins, (right side on the map of High Gate Ruins where the door to Vokun's Throne Room is on the left side). Climb as high as possible, to be about the same height as the platform on the opposite side. Then use Whirlwind Sprint to get on to the platform. Wait by the gate and the follower should come to the other side of the gate. Then ask them to pull the chain with "Talk to ..." and "I need you to do something."
 * If the follower does not show up on the other side, it's still possible to get in. Get the follower up the platform by waiting and have them stand by the door. The Unrelenting Force shout can blow them through the door. After that, tell the follower to open the gate.
 * Lost Valkygg, in the large chest near the deep hole and a Draugr Deathlord.
 * Ragnvald - after defeating Otar the Mad, the Dragon Priest.
 * Skuldafn - located in a chest amongst rubble.
 * Valthume - in the chest in front of the Word Wall.
 * Volskygge - in a chest by the throne of the final Draugr boss before the mountain top exit.
 * Castle Volkihar - on a rack in the room Harkon sits in.

Bugs
Kavohzein's Fang may be found before the Alteration Ritual Spell has been accepted. As it is a quest item, it will become stuck in the inventory until the quest has been completed. It can, however, be removed from the inventory if placed on a weapon rack or in an active display case in a house.
