Languages and access

The game has ten language entry points: English, Korean, Japanese, Traditional Chinese, Simplified Chinese, Vietnamese, French, Thai, Spanish and German. English is at the root URL, without /en. Some newer mechanics still use English fallback text; complete translation parity is not claimed.

This reference library is currently in English. Links back to the game offer all ten languages. Public game pages support iframe embedding; a browser may partition embedded storage separately from direct visits.
