Sunhallowed Elven Arrows are a unique variant of Elven Arrows found in The Elder Scrolls V: Dawnguard. The arrows have glowing white tips with white fletching, and are stored in a silver Elven quiver, used only by the Snow Elves.
In order to obtain additional arrows, Gelebor provides a service where he will bless normal Elven Arrows with incantations and rituals to produce Sunhallowed Elven Arrows in groups of twenty. A good source for Elven Arrows is Sorine Jurard. She typically sells around 200 at a time, but is only available as a merchant if the Dawnguard are sided with. If sided with the Volkihar Clan, Elven Arrows can instead be purchased from Hestla, who carries roughly the same amount. Alternatively, Elven Arrows can be smithed using firewood and refined moonstone, provided the Dragonborn has acquired the Elven Smithing perk.
These arrows are unique in that they produce a unique effect when fired from Auriel's Bow. When fired normally at an undead enemy, the arrows cause Sun Damage and a small area-of-effect blast that will cause some damage to surrounding entities.
Shooting a Sunhallowed Arrow from Auriel's Bow at the sun will cause the sun to undergo an explosion, causing beams of harmful sunlight to rain down on all enemies (and allies) similar to the effect of the Storm Call shout.
These special effects only occur when the arrows are fired from Auriel's Bow. When fired from any other bow, they will behave just like the normal elven arrows.
During the battle with Lord Harkon, the Sunhallowed Arrows do not have to be fired. Auriel's Bow has the ability to destroy the barrier he uses to heal himself. Otherwise, he is untouchable while he heals.
- Unlike other Arrows, the Sunhallowed Elven Arrows do not become infinite when given to a follower like Aela the Huntress.
- Unlike a follower, if you go to Solitude and make your way next to the legion headquarters there will be a guard with a bow practicing shooting arrows at a bulls-eye stand, sneak behind him even in daylight just wait till it shows hidden, pickpocket him and leave 1 arrow, you can leave the city and comeback in a few in game hours and he will be launching those infinite arrows which you can take.
