Evolution and form requirements
The Evolution Quests page records Eyepatch as the resulting evolution item. Read the owned unit's recipe before consuming it.
Equipment and team decisions
The wiki recommends a four-player group for the EX-stage requirement. Byeken's raw base entry is Secret, Unbound, costs 2,200 Yen and has three placements. The PvP wins are part of this quest's progression and are not interchangeable with ordinary Story wins.
Trading and value
Only trade an item the in-game trade window permits. Limited units that remain obtainable cannot yet be traded. Levels and stats transfer; Update 15.0 removed Unit Ascension bonuses, so previously ascended units no longer receive those bonuses; traits and pity do not. Community value estimates describe the exact normal/shiny/form variant and are opinions rather than developer prices.
