Sanguine Rose (Skyrim)

The staff is given as a reward for completing the daedric quest A Night to Remember.

Requirements
The player must be at least Level 14 to begin the quest. The quest rewards the player with the Sanguine Rose. It is given to the player by the "drinking buddy" Sam Guevenne who turns out to be the Daedric Prince Sanguine.

Effects
The Rose summons a Dremora Kynmarcher, Dremora Valkynaz or a Dremora Markynaz and on rare occasions it will summon the daedric prince Sanguine (depending on players level) to fight for the Dragonborn for 60 seconds. Killing the Dremora that is summoned will not provide you with a Daedric Heart as you cannot loot the body for it dissolves.

Bugs

 * When left in a chest (such as in a player home) for long periods of time it is possible that when you remove it from the chest and equip it, it will no longer summon a Dremora. The sound effects can be heard but no Dremora will appear.
 * Having the perk "Elemental Potency" may also cause the staff to malfunction.
 * If you kill the Dremora you summon and happen to get a death animation of cutting its head off, it will remain headless the next time it is summoned. (360. Possibly PC)
