Tips and Strategies

Retrieve the Power Cell inside All-Mother Mountain

Power Cells are needed to complete the Ancient Armory questline and acquire the powerful Shield-Weaver Outfit.

This first Power Cell will be hard to retrieve after this mission, so make sure to grab it before exiting All-Mother Mountain.

1	After exiting the room where you retrieved Aloy's equipment, go to the opposite end of the bonfire room.
2	There should be a vent to your left. Crouch down and follow the vent into a secret room.
3	Retrieve the Power Cell on the ground. This will start the Ancient Armory questline.

Loot the Area Before Speaking to Resh

In order to prepare for the fight with the Corruptor, make sure to explore the entire area before speaking to Resh.

Plenty of Ridge-Wood, Medicinal Herbs, and Supply Crates litter the area, allowing you to start the Corruptor fight with an advantage.

Use a Ropecaster to Quickly Deal with Striders

Corrupted Striders will leave corrupted patches on the ground whenever they run or charge around the area. These will inflict damage should Aloy run over them.

Use a Ropecaster to quickly tie down the rampaging Striders, minimizing the damage they can deal during the fight.

Overheat the Corruptor Using Fire Arrows

Corruptors are weak to fire damage. Use your Fire Arrows to set it alight. Remember, it is not worth it to waste regular arrows trying to breach its thick armor.

Note: Pay attention to the small thermometer icon next to the Fire Indicator. This will fill up as the Corruptor takes more and more fire damage.

Destroy the Cooling Rod to Inflict Massive Damage

Once the Thermometer Icon fills up, a yellow cylinder will pop-up just above the Corruptor's eye. This is the Cooling Rod.

Shoot it to deal massive damage to the Corruptor. Due to how wild the Machine's movements are, it is recommended that players learn the Concentration Skill prior to the fight.
