Ratatan Update v0.6.3 Adds Super Fever Tech and Cobun Accessories
Ratatan version v0.6.3 introduces Super Fever Tech abilities for all units, Cobun accessories, and major balance passes for Fire and Poison elements. The update also removes Welcome Mode from multiplayer and adjusts damage formulas.
Ratatan version v0.6.3 brings a major feature drop alongside sweeping battle balance changes, elemental card reworks, and economy adjustments. Players can now unlock and unleash Super Fever Techs through the Quest Board when the Tension Gauge is full, utilizing unique skills for each Ratatan unit. Alongside combat changes, the update introduces Cobun accessories, room lists for random matchmaking, and automated save-data backups.
Super Fever Tech and Combat Adjustments
When the Tension Gauge is full, players can input specific rhythm commands to consume tension and activate new Super Fever Techs. These abilities range from Harigittan building defensive towers to Mimizukyun firing ice arrows. To accommodate these additions, the damage formula has been updated, and telegraph markers on enemy attacks now better match actual hitboxes. High-difficulty phases feature increased spacing between enemies, and ranged enemy projectiles are easier to avoid. Additionally, Welcome Mode is disabled in multiplayer to maintain consistent balance.
Element and Economy Reworks
Fire and Poison elements receive substantial buffs to make damage types more distinct. Poison duration increases from 6 to 18 seconds, with total damage scaling up significantly. Fire card effects boosting normal attacks and hustle tech are enhanced, and condition thresholds are relaxed. In the economy, Divine Draw no longer dispenses tokens to prevent excessive shop upgrades, but players can now spend tokens to reroll Ratakaruta cards.
Cobun Upgrades and Quality of Life
Players can now equip accessories on Cobun from the squad and formation screen to alter appearances and grant stat bonuses. Ratatan Dock upgrades now increase tension gauge gain and MP recovery on just inputs. Furthermore, boss HP bars now display localized names, and save-data backups automatically load if the primary save becomes corrupted.
Why this patch matters
Version v0.6.3 deepens combat options with Super Fever moves and elemental buffs while reining in economy exploits and fixing recurring multiplayer friction.
