 Detailed Walkthrough
 Kahvozein's Fang
To start this quest, you must have an Alteration skill of 90 or higher. Speak with Tolfdir, and ask if there is anything new he can teach you. He tells you he has been working on a new spell, but to complete his research, he needs heartscales cut from a dragon's skeleton, which can only be done using a dagger called Kahvozein's Fang. He tasks you with retrieving the blade, which can be found in a radiant dragon priest dungeon.
 The Heartscales
Once you have the dagger, you must locate a dragon's corpse, either by killing one or finding the remains of a previously-deceased dragon. It is not necessary to slay a dragon using Kahvozein's Fang; you need only equip the dagger in your right hand (it won't work with your left hand) and loot the creature's corpse. The heartscales will automatically be added to your inventory.
- It is possible to find Kahvozein's Fang in a dungeon and collect heartscales from a dragon's corpse before the quest is given.
- Once the quest is complete, you can continue to use the Fang to collect a heartscale from each dragon corpse, in addition to the standard dragon loot. These scales can't be used for crafting, but are no longer quest items and can be sold to vendors.
- It is necessary to complete Dragon Rising in order to find a dragon suitable for heartscale harvesting. Although the Skeletal Dragon and Durnehviir can be found and defeated beforehand, neither yield scales of any kind.
- In your quest log, this quest is mistakenly decorated with the Side Quests knotwork (as displayed in the quest header), instead of the correct College of Winterhold knotwork that is shown on all other college quests. This does not have any known effect on gameplay. In particular, this quest is not considered to be a Side Quest for the purpose of the Sideways achievement.
Mod Notes: The quest Type is "None" instead of "Mages Guild"
- This bug is fixed by version 1.2.1 of the Unofficial Skyrim Patch.
- After retrieving the heart scales, it is possible that you will not be able to talk to Tolfdir and you will be unable to finish the quest.
