How idle progression works
What continues while you are away, what does not, and how active and idle play fit together.
Your first demo session
A spoiler-light walkthrough of equipment, upgrades, abilities, world bosses, and useful early priorities.
Our fair-gacha rules
Published probabilities, visible pity, premium currency, and the boundaries we set for monetization.
Why we built The Last Echo
A development note about combining idle convenience with meaningful RPG decisions.
What these guides cover
The Last Echo is still in active development, so these pages describe the current TestFlight demo rather than promising a final feature set. When a balance value or system changes, we update the relevant guide and its date. That makes the handbook useful to players and keeps our public explanations accountable to the game itself.
