WHERE & HOW TO FARM
Buy later special weapon stones
Polendina at Hotel Krat, after delivering the Special Krat Supply Box from Collapsed Street.
Before you go
- Reach Collapsed Street and locate the Special Krat Supply Box.
- Return to Hotel Krat and deliver the box to Polendina.
- Have sufficient Ergo for the chosen item.
- Own or plan to upgrade a special weapon that needs the selected tier.
Farming steps
- Search Collapsed Street and collect the Special Krat Supply Box from its chapter route.
- Travel back to Hotel Krat and speak with Polendina.
- Deliver the box so his inventory expands.
- Open his shop and check for Dark Moonstones of the Covenant and a Full Moonstone of the Covenant.
- At the weapon enhancement menu, inspect the next upgrade for your chosen special weapon.
- Compare the requested tier with Polendina’s stock and buy only the material that advances that weapon.
- Return to enhancement and apply the stone when you are ready.
- Keep rare materials unspent until you settle on a special weapon; the same stone may be valuable for another option.
- The recorded Full Moonstone price is 6,500 Ergo and the Dark Moonstone price is 2,080 Ergo; confirm current shop display before purchasing.
Repeat, collect and use
Delivering the supply box is one-time. Added shop stock is limited, so purchases are not a renewable farm.
Common mistakes
- Do not expect expanded stock before delivering the box.
- Do not buy a normal weapon Moonstone for a special weapon; match the Covenant family and tier.
- Do not assume the shop replenishes after purchase; budget for the limited stock.
When to stop or switch
Stop once you buy the material required for the next special weapon upgrade or the relevant stock runs out.
