Many players are curious on how long it would take for the offline mode in case you just leave or not log in the game. You can play offline for up to 8 hours max in progressing stages !

And when you are in offline mode without any buffs from mastery point or relic, one stage takes 60 second to pass.

Additionally, if you are looking for the lowest level of offline mode that could pass a stage is up to 15 second by using mastery points and relics related with decreasing the time of offline mode !!
