Korean servers only. Steam/PURPLE Global and Taiwan have separate update schedules.
The October 7 Korea patch changed the Soul Crystal reward for spending a key on a Hidden Cube from 100 to 1,000. This tenfold increase applies to the specified keyed reward, not to every Soul Crystal source.
A credit for Chapter 1 players
Korean players who used Hidden Cube keys to collect the previous reward during Chapter 1 are covered by a retroactive adjustment. The publisher plans to calculate the additional Soul Crystals using historical game logs. The patch notes do not specify the exact delivery time for individual accounts, so the announcement should not be taken as proof that every adjustment is already complete.
Keep regional rules separate
This item is different from the same patch’s refining-stone, merchant and daily-dungeon adjustments, which have their own conditions. Players outside Korea should follow their own region’s notes rather than assuming the 1,000-crystal amount or compensation policy also applies to their servers.
