Skyrim:Blade of Sacrifice
|Unique Item: Blade of Sacrifice (00079b1d)
The Blade of Sacrifice is a ceremonial ebony dagger given to you by a Priestess of Boethiah as part of Boethiah's Calling. She will give the dagger with the intention that you use it to kill a follower on the Altar of Sacrifice located at the Sacellum of Boethiah, as part of a ritual to summon the Daedric Prince. Although the priestess will say you must use this ritualistic weapon to complete the ceremony, any weapon may be used. Tempering this dagger requires one ebony ingot. The Blade of Sacrifice cannot be enchanted.
Speaking to one of the cultists about who is Boethiah will have her tell you about the Prince, and state that he only cares for those who are driven and have performed many notable feats. Claiming to meet this description will have her respond: "If you desire a glimpse of our Dark Mistress, then this is what you must do. First, prove your tongue can wield a lie. Find someone. Gain his trust. Lead him to the shrine above. Next, instruct your thrall to touch the Pillar of Sacrifice. Its magic will ensnare him, rendering him helpless. Then, girded with certitude, plant the ceremonial blade deeply, so that the waters of his heart wash over you. If your will is strong enough, it will stir Boethiah in her Dark Mansion, and she will appear before us." Agreeing to do this and successfully completing the ceremony will indeed summon the Daedra, with his first command being to slaughter all of the other cultists.
