Daedra Heart (Skyrim)

Characteristics
Daedra Hearts are the key ingredient used in crafting Daedric Armor and can also be used to create potions. They are relatively rare and quite valuable. However, several Alchemy shops carry them and refresh stock every 48 hours. A few are found in the quests to obtain Daedric artifacts while others can be found in random apothecary satchels and on necromancers.

If the Dragonborn possesses the Sigil Stone, Daedra Hearts can be created by using the Atronach Forge in the Midden under the College of Winterhold by putting one human heart and a filled Black Soul Gem in the offering box, then using the pullbar to create a Daedra Heart. Daedra hearts can also be found in Enthir's store located in the Hall of Attainment in the College of Winterhold.

Recurring

 * Shrine of Mehrunes Dagon, during Pieces of the Past. Four Dremora (two inside, two outside), each possessing one Daedra heart. The four Dremora respawn once each in-game week.
 * Shrine of Azura quest, upon entering the star and defeating dremora.
 * Nightcaller Temple, during Waking Nightmare. In the alchemy laboratory area, on the shelves amongst the other reagents.
 * Enthir, at the College of Winterhold, sells two at a time and will restock every two days. He must be approached first, and then met in his room on the second floor of the Hall of Attainment (first room on the left). The player will lose the option to barter with him if he fails to approach him before the College of Winterhold questline is completed. This issue will fix itself after the Thieves Guild questline is completed.
 * If the Dragonborn has never bartered with Enthir and has completed the College of Winterhold questline, wearing the Archmage's Robes and talking with him will fix the issue (PS3, does not work for Xbox 360 or PC). Bartering with him as a fence for the Thieve's Guild can prevent him from having the Daedra Hearts because he can no longer be found at the College, but at The Frozen Hearth instead (PS3).
 * Jorrvaskr. In the room where Kodlak is found, on or near a plate on the desk.
 * Respawns at the beginning of each month.
 * Counts as stolen unless The Companions' questline has been completed.
 * A second Daedra Heart may sometimes be pickpocketed from Kodlak.
 * Hall of the Vigilant. On the table at the far end of the main room.
 * Sinderion's Field Laboratory in Blackreach. On a shelf to the left of the laboratory entrance.
 * In a random encounter, a thief who is caught bothering a child may drop one after being killed by city guards.
 * Dark Brotherhood. Babbette usually sells Daedra Heart
