Once Human Iridium Crystal Guide: Best Chalk Peak Farming Spots and Uses

Iridium Crystal becomes important once Once Human starts pushing players toward stronger Tier IV equipment. It is not something you casually trip over in the starter zones, unless the game is feeling unusually generous. To gather it reliably, head for Chalk Peak and plan around higher-level exploration.

Where to Farm Iridium Crystal

Iridium Crystal can be farmed in the Chalk Peak region. The game may warn Meta-humans who enter this area before progressing far enough through the main quests, so do not treat Chalk Peak like an early sightseeing trip.

A Level 31 or higher character is recommended before exploring the region. Once you can handle the area, check these locations for Iridium Crystal and other useful resources:

• Holt Town
• Furnace Lair
• Gaia Military Base
• Evergreen Vineyard
• Rotten Saddle
• Monolith of Thirst
• Alpha Institute
• Silvershore Resort

Another source is The Wanderer, the giant bus-like Deviant that moves around on hands. Players can loot The Wanderer once per day, so collect from its container in Chalk Peak when available, then wait for the daily respawn before trying again.
