Weekly Progression
Eriu Seal weekly mission route
A weekly Eriu Raid Battle objective can turn repeated eligible clears into Eriu Seals for targeted material exchanges.
Weekly Missions panel, on the Eriu Raid Battle completion objective; use the Eriu Seal Shop for exchanges.
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.
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.
