Ratatan December Preview Details Dark Ratatan Battles and Duo System
Ratatan outlines its upcoming December update, introducing Dark Ratatan battles, Episode 2 story content, and the Duo Ratakaruta system. The patch also adds the Goddess Gacha and matchmaking improvements.
The development team behind Ratatan has shared a progress update for the upcoming major patch, targeting a late December release. The update bridges the current roguelite structure directly into next spring's To the Everafter content.
Dark Ratatan Events and Boss Fights
Episode 2 unlocks after clearing World 5, integrating story events directly into roguelite progression. Dark Ratatan boss fights feature original musical tracks and command Dark Cobun through musical cues. Defeating these high-difficulty bosses yields Mythic-tier gear.
Ratakaruta Duo System and Goddess Gacha
A new Duo feature allows players to combine elemental forces beyond specific thresholds to access powerful Duo Ratakaruta, limited to one per run. Additionally, the Goddess Gacha lets players convert surplus equipment and materials into points for gacha pulls featuring exclusive items.
Multiplayer and Accessories
Online random match lobbies now feature a refresh button and the ability to enter any available room. A new Legendary accessory rarity is introduced, featuring random Decorune effects for build crafting.
Why this patch matters
This preview sets expectations for a substantial content injection that deepens both the narrative integration and build variety of Ratatan.
