Players who purchased the main package before it became free can receive the Chapter-8 content for free, so there is no need to purchase this DLC.

Chapter-8 includes the following three stages.

[8-1 Phantom Tactical Town]

[8-2 Lit Tactical Palace]

[8-3 Mirrors Tactical Labyrinth]

8-4 (very hard) Traditional Tactical Moon

(Often delayed in schedule)

It is recommended that you have 800+ Sunstone before purchasing this DLC.
