Equipment and materials
Farm a boss material from battlefield rewards
Targeting the battlefield that lists the material you need prevents wasted boss clears and supports focused equipment improvement.
Blacksmith to identify the material, then the battlefield map and reward panel for the matching mission.
Repeatable by replaying an unlocked battlefield, but the reward depends on its current panel and completion. Enemy drops are not guaranteed quantities.
Stop when you have the materials for the chosen improvement, or switch to another listed battlefield if the current clear is unreliable.
