An idle RPG asks players to invest time before they can see everything the game contains. That makes hidden progression dangerous. If the interface shows only the two upgrades available today, a player can reasonably assume those are the entire game.
The Unfinished Kingdom had that problem. Attack and Health worked, but the longer path lived mostly in design documents. We have been moving that path into the game itself.
Locked does not need to mean secret
The Warden Growth panel now shows Health Regen, Skill Power, Critical Hits, and Attack Speed before every stat is available. Each row explains the Cairn requirement and distinguishes a playable upgrade from a requirement that has been reached while its feature is still in development.
That wording matters. A visible name can create excitement, but presenting unfinished work as available breaks trust. The interface uses separate states for locked, available, and requirement met. Players can see the road ahead without being promised a button that does nothing.
The first advanced stats need clear jobs
Health Regen unlocks after the first Bellkeeper. The Warden already recovers a small amount after each victory, and every level adds directly to that recovery. The panel shows both the bonus and the total so the purchase is understandable before any Fragments are spent.
Skill Power unlocks at Cairn 150. It strengthens the four active skills while leaving automatic attacks alone. Strike and Core deal more damage, Repair restores more Health, and Guard lasts longer. This gives active play its own progression path instead of turning Skill Power into another name for Attack.
Both stats use the same purchase controls as the core upgrades. The player can request one level, ten levels, or the maximum affordable amount. The button reports how many levels can actually be bought and the exact Fragment cost.
Resonances show a different kind of growth
Permanent numbers are only one part of the plan. Temporary Resonance alignment now begins after the first Bellkeeper. The first alignment, Boot, extends Guard and improves Repair. The other four Resonances remain visible with their sector requirements and development status.
This creates two readable paths. Warden Growth provides permanent improvements purchased with Fragments. Resonances change the character of combat as the Warden moves through larger regions. Later systems can build on both without hiding the structure until the player reaches it.
Every visible number has to survive a save
Adding a purchase button is the small part. Advanced growth also needs save migration, cloud validation, rollback protection, exact currency accounting, and tests that prove old saves load with safe defaults.
The server now checks each advanced level against its unlock requirement, Fragment cost, and Score gain. A stale or modified browser cannot add free levels to an account-backed Warden. The interface, simulation, saved state, and server rules all use the same cost curves.
The remaining growth stats still need implementation and balance work. The important change is that the game now admits they exist. Players can see that Attack and Health are the beginning of the Warden's progression rather than the end of it.
