Bloodcursed Elven Arrow

Bloodcursed Elven Arrow are a unique variant of Elven Arrows found in.

Acquisition
Upon completion of Touching the Sky, Serana provides a service where she converts normal Elven Arrows into Bloodcursed Elven Arrows in groups of twenty.

Large supplies of Elven Arrows appear in both Fort Dawnguard and Castle Volkihar.

The Dawnguard's vendor is Sorine Jurard, and the vampire's blacksmith is Hestla. Both typically carry around 200 at a time.

Enchantment
Its effect acts opposite to Sunhallowed Elven Arrows for which Auriel's Bow is intended.

Shooting a Bloodcursed Arrow from Auriel's Bow at the sun will blot it out for a single day. These special effects only occur when the arrows are fired from Auriel's Bow. When fired from any other bow, they behave similar to the normal Elven arrows.

Usefulness
Vampires, whose attributes are stunted by sunlight, have a decreased regeneration rate of Health, Magicka, and Stamina while using these weapons.

Trivia

 * When the sky is cloudy and the sun is difficult to locate, use Clear Skies to reveal the sun again.
 * When the bow's aim is close from the sun, with the Auriel's Bow and Bloodcursed Elven Arrow, the sky becomes red-orange for a moment to indicate where the sun is.
