Chat, online co-op and PVP
Harassment, hate, threats, sexual abuse, child sexual exploitation, illegal content, disclosure of personal information, spam and impersonation are prohibited. Tap a nickname to report/block a user or delete your own message; Manage Blocks permits unblocking. Reports receive human review; report totals do not automatically cause penalties. Contact grow29971@gmail.com for reasons, removal requests or appeals. Online rooms use a six-digit invitation code. Lobbies and ordinary dungeons are private by default, with profiles and combat information relayed only when joining a sortie, duel or raid. Do not publish room codes or personal information in chat.
Play and storage
Signing in alone does not synchronize progress between devices. Be careful when clearing browser data, resetting or uninstalling. Disable flashes and screen shake in settings and take a break if uncomfortable. The game contains violent combat and moving visual effects.
