Finding Classic mode
Accounts with Classic access can find the entry in the manager menu. It is not necessarily available to every account or channel. After entering once, an entry may also appear during later loading. If it is missing, check your channel, version and access status rather than downloading an unknown old package.
Keep the two rule sets separate
This guide’s recipes, hero bases and monster drops describe the main game. Classic has its own battle, reward, recipe and save rules. Main-game recipes do not explain Classic research, and recovery stories about the old standalone app do not guarantee recovery in the integrated mode.
Changing devices or investigating a save
Record your player/account identifier, channel, version, device and last known good save time. Confirm binding and recovery for that account before changing devices. If progress looks wrong, preserve screenshots and avoid clearing data, overwriting saves or repeatedly reinstalling. Tell support which mode is affected.
