WHERE & HOW TO FARM
Where to farm
Unjust Cathedral, the level-125 raid battle.
Use Unjust Cathedral when Eriu advancement is your priority. The battle can supply Eriu materials, while weekly missions and Eriu Seals give you additional ways to make progress. Random raid rewards and mission rewards are separate: a clear can advance the weekly count even if it does not drop the item you want. Before repeating the raid, identify the exact stone, fragment, or other ingredient shown on your equipment’s advancement screen.

Open the Eriu equipment advancement panel and note the missing materials for the specific item.
Select Unjust Cathedral from the battle list and check the displayed entry conditions.
Complete the raid and inspect the reward inventory for Eriu advancement items, fragments, crystals, or other useful materials.
Open Manage Rewards and verify whether the clear counted toward the Unjust Cathedral weekly mission.
Collect Eriu Seals from eligible missions, then inspect the Eriu Seal Shop for an exchange matching your remaining need.
Use the collected materials in the advancement interface once the listed requirement is complete.
Farming tips
Equipment advancement is a guaranteed process once all displayed materials are present; the raid drops themselves are not guaranteed.
If a weekly reward choice is available, compare its contents with the missing ingredient before selecting it.
Repeat, collect and use
Repeat the raid when entries and weekly progress make it worthwhile. The weekly mission has a finite clear count; the raid remains a chance-based source outside that mission.
Common mistakes
Expecting every clear to produce a needed material: treat drops as chance-based and build progress through seals and weekly rewards too.
Buying an exchange item before checking the equipment panel: compare the shop item with the exact missing material first.
Confusing weekly mission completion with reward selection: track the mission, then select the reward when the interface makes it available.
When to stop or switch
Stop direct farming when the advancement panel has every required item. If it does not, compare the Seal Shop and available weekly reward before spending more raid entries.
