- "An arrow created using ancient technology ancient technology. To be struck with one is to be consigned to oblivion in an instant. It deals devastating damage-even against Guardians."
- — Hyrule Compendium
Ancient Arrows are items from The Legend of Zelda: Breath of the Wild. They are a type of specialty ammunition for the bows, and are created using Ancient Sheikah technology. If any non-boss or non-Guardian enemy is struck by one, they will be blasted into oblivion in an instant, without a trace. Against Guardians, Ancient Arrows deal particularly devastating damage, being crafted from the same technology, and a single arrow directly to the eye can instantly destroy almost any guardian enemy, although that is not the case with bosses. Though powerful, using them on wildlife or common enemies prevents them from dropping materials and/or weapons as they are obliterated when hit. However Guardians will drop still drop Guardian Parts when killed with one.
One of these is given by Beedle and another one is given by Robbie in exchange for ancient parts materials. After completing the side quest "Robbie's Research", Cherry can forge Ancient Arrows at the Akkala Ancient Tech Lab.
A single Ancient Arrow costs 90 Rupees, 2 Ancient Screws, 1 Ancient Shaft, and 1 Arrow. A bundle of three Ancient Arrows costs 250 Rupees, 6 Ancient Screws, 3 Ancient Shafts, and 3 Arrows. A bundle of five Ancient Arrows costs 400 Rupees, 5 Ancient Springs, 5 Ancient Shafts, and 5 Arrows.
Ancient Arrows are the only non-holy weaponry (the Master Sword, Bow of Light, and Twilight Bow) that can harm Dark Beast Ganon. Link can add its picture to the Hyrule Compendium by shooting an Ancient Arrow at the ground, then taking the Ancient Arrow's picture with the Camera Rune as it is lying on the ground. The Hyrule Compendium's additional effects section for the Ancient Arrow states "The ancient arrowhead deals massive damage".
The Ancient Arrow was first introduced in the 2014 E3 trailer, where Link is shown readying an Ancient Arrow to his Traveler's Bow, ready to attack a pursuing Guardian.
