A weekly Eriu Raid Battle objective can turn repeated eligible clears into Eriu Seals for targeted material exchanges.
PC / Global (Nexon America)
WHERE & HOW TO FARM
Where to farm
Weekly Missions panel, on the Eriu Raid Battle completion objective; use the Eriu Seal Shop for exchanges.
Eriu Seals provide a shop path toward Eriu equipment materials, complementing the chance-based drops from Unjust Cathedral. The mission objective is part of the weekly mission slate and can change, so check its displayed count and reward before committing runs. This route is especially useful when a seal exchange matches the exact stone or fragment missing from an advancement plan. Treat the mission count as the collection target, then spend the reward deliberately.

Check the Eriu advancement screen and identify which shop exchange would help your target.
Complete the listed Eriu raid battle and return to the mission panel to verify progress.
Repeat eligible clears until the displayed objective is complete.

Farming tips
Mission conditions and payouts can change by update, so rely on the active objective display.
Keep seals until you know which Eriu item is missing; they support targeted shop choices.
Repeat, collect and use
This is a limited weekly mission route. It repeats only when the Eriu Raid Battle objective appears in a later weekly slate; seal collection is not an unlimited reward per clear.
Common mistakes
Assuming an old required count: use the current mission panel’s count.
Spending seals before checking material requirements: identify the item on the advancement screen first.
Counting a battle that did not satisfy the listed objective: verify progress after each run.
When to stop or switch
Stop once the current mission reward is claimed and the needed exchange is made or the seals are being saved for a known target. Switch to Unjust Cathedral direct farming if you still need chance-based Eriu materials.
