Two Oseram tinkers in Chainscrape have offered to build Aloy a powerful new weapon if she can get them the right part


  1. Gather Charger Horns 0/3
  2. Gather a Fanhron Rib
  3. Deliver the parts to Delah

Gather Charger Horns 0/3

Once you first reach Chainscrape settlement, walk over to the gates to the southwest and you’ll find Delah at her workbench. Speak with her and she’ll request that you get three Charger Horns and one Fanghorn Rib. Exit the settlement and you’ll find multiple Chargers roaming the open field. Here you’ll want to focus your shots onto their horns to detach them, then finish it off by shooting at the canisters on it’s back or using shock arrows.

(1 of 3) Head to this location to find Delah

Gather a Fanhron Rib

After you’ve acquired the three Charger Horns, return to the settlement, then head southeast across the wooden bridge to find Fanghorns that you’ll need to take down first and collect the Rib from the body. If you have any Blastsling Ammo left, then use that as it’s weak to Frost Damage. If not, then focus your arrows towards it’s canisters on it’s back or horns.

Deliver the parts to Delah

Once you’ve acquired both the Fanhron Rib and Charger Horns, return to Delah at the Chainscrape Settlement and give them to her in order to acquire the Prototype Spike Thrower.
