Eternal arrows are bow ammunition that never runs out. Each shot spends Mana rather than consuming an arrow, so a single eternal arrow equipped in your ammo slot keeps firing for as long as you have Mana. There are eleven across four damage types, split between two crafting survivors. Mages get the same idea for spells: see how to get Eternal spells.
Quick answer: Craft eternal arrows one at a time — nine at the Hunter under a roof and two Giant Bone versions at the Collector.
How eternal arrows work
The item description spells out the mechanic directly:
Eternal Arrow: Does not deplete Ammo per use. Equip the Eternal Arrow and use Mana to shoot it with a Bow.
The ammo selector places an infinity symbol beside an eternal arrow’s name. Since firing never consumes it, this ammunition suits extended battles with a single target; its three elemental variants also let you exploit an enemy’s weakness.
Where to craft them and what unlocks each recipe
Craft Hunter arrows only beneath a roof, so move to a covered area before making them. Most recipes unlock automatically when you collect a particular material, which is identified in each arrow’s entry below.
Two of the arrows are also handed out as quest rewards, so you can get them without gathering ingredients first. Eternal Frost Arrow I comes from the quest “Eternally Piercing”, and Eternal Frost Arrow III from the Hunter’s quest “Magically Empowered Equipment”.

Both arrows gain a −6% Mana Cost enhancement at ranks 46 and 47. Ranged Critical Strike Chance then rises by +2% at 48 and +3% at 49. At rank 50, the Frost arrow adds +10% All Magic Ice Damage, while the Voltaic arrow adds +10% All Magic Shock Damage. Eternal Giant Bone Arrow I can reach level 40, gaining a Mana Cost enhancement, +3% Ranged Critical Strike Chance, and +5% All Blunt Damage along the way.
