・Purgatorium Dungeon Added!

During the event period, the warding dungeon [Assault! Dragon Ark Tenshou -Puragtorium-] will be available. Purgatorium dungeons appear irregularly, but you can get the exclusive Purgatorium Treasure items!

■Concerning Purgatorium Dungeons 　・The monsters have high resistances, and attacks other than super effective attacks will be less effective. 　　Additionally, these monsters will have extra strong attacks. 　・Clear the dungeon with a B Rank or higher to be awarded Purgatorium Treasures. 　・Occasionally when clearing at the highest difficulty, you can get a rare Magatama!

■About Items from the Dragon Ark Tenshou Purgatorium dungeon 　・The Dragon Ark Tenshou Purgatorium Boss will drop the following items:

　　　Normal Difficulty → Purgatorium Tenryuu's Dagger 　　　Hard Difficulty → Pugatorium Tenryuu's Fittings 　　　Hell Difficulty → Purgatorium Tenryuu's Ruby

■Concerning Purgatorium Treasure

・Purgatorium treasures can be exchanged with the purgatorium treasure NPC in Onigashima. ・Clear each difficulty of the Purgatorium dungeon once in order to open the Exchange. ・The purgatorium treasure NPC is only available when the purgatorium dungeon is available, and the items available in the exchange vary depending on which purgatorium is available. ・Purgatorium treasures will convert to purgatorium junk when the purgatorium dungeon is no longer available, but the purgatorium junk can be exchanged for treasures with the NPC.

▼Exchange Item Sample

■Unlocking Purgatorium Dungeons Plater must clear the [To Kishinden] quest and speak to the NPC Chifuri in the Temporal Rift in order to open these dungeons.

◆Dungeon Availability 　After maintenance 10/1/2026 JST 　Until maintenance 10/15/2026 JST

・We will reset the exchange history for the recipe items currently available in the Exchange Shop for the ongoing event Akitsu, Kusatsu, and the Peerless. 　※This measure is intended as a relief measure for players who accidentally discarded recipes they had already exchanged for.

　We are also aware of an issue where items obtained not only from Exchange Shops, but also through quests and other means, may become unobtainable again after being discarded. The Service Team is continuing to consider measures to address this issue.

---

[Addendum] ・Added the NPC Vit Daruma to the Onigashima. 　

　The Onigiri collaboration event will begin in the community-built sandbox game TERAVIT on 10/1/2026 JST! 　A minigame world recreating Onigashima and skins that let you dress up as Onigiri characters will be available. In addition, an Onigiri-themed Creators Grand Prix will be held at the same time!
