■ It
becomes possible to apply for participation from Parch 3.56 "Alexander Creator Savage" as an update content finder.

· The mechanism by which the degree of capture progress is recorded after each layer capture is abolished.

- The strategy order of each layer has been abolished and you can capture from any layer.

· Two treasure boxes will surely appear and the weekly limit for items gained from treasure boxes will be eliminated.

· "Exceeding power" will come to occur. A force exceeding the time of content entry occurs, and the maximum HP / applied damage / recovery magic effect amount increases by 10%.
　※ Restart does not increase the effect.

Finally. Should be without lockout since they added Diadem imho.
