Horizon Forbidden West’s sidequests are separated into two categories: Side and Errands. As if the game doesn’t already have more than enough activities to do, completing these will earn players XP, Skill Points to use in the skill tree, and sometimes, powerful new weapons to add to Aloy’s machine-killing arsenal. In the town of Chainscrape, players can find a newErrand called “A Bigger Boom” once the shops and merchants open up after thestory mission “To the Brink"has been finished.

Where to Find Fanghorn Rib
Toget a Fanghorn Rib, head to the area southeast of Chainscrape. If players have the errand activated in the menu, there should be two yellow circles. Go to the east-most circle andsearch for Fire Fanghorn enemies.Defeating them will drop the Fanghorn Rib.
Players should use their focus with the right stick to check the machine name to make sure it’s the correct one. Once the Fanghorn is defeated, go up to it and hold Triangle to grab its loot.

How to Get Charger Horns
Now, from the Fire Fanghorn area,head east to the Charger Mount Site. There will be plenty of Charger’s walking about, but still, make sure to use thefocus ability to check the machine names. Theonly way to get Charger Horns is to break off its horns by inflicting Tear damage. If the machine dies before its horns get detached, players won’t be able to loot the material for the quest. Use an arrow type with strong tear damage, and the horns should fall off in one or two hits. Grab three of the Charger Horns and return to Delah and her sister for a reward.
