Best upgrade order

September planning references

The progression directory now includes September biome reports, supported Rift egg pools and the official Revenge event schedule. Use these alongside the evergreen decision steps below. The guide’s revision date is separate from the dated evidence on individual records.

Map the confirmed systems

The current official description names treadmill upgrades, base upgrades, and treadmill training that grants speed. Official badge metadata also includes an Angelic Treadmill achievement, confirming that treadmill progression is a meaningful part of the experience. These sources do not establish every tier, cost, prerequisite, or effect, so those values stay outside this guide.

Open the current upgrade surfaces in your own session and note only what they show. Separate a permanent improvement from training activity, and separate base capacity or protection from pet income. Clear categories make it easier to compare the result of one decision without attributing every change to the newest purchase.

Use a bottleneck-first order

A good upgrade order begins with a repeated failure. If travel takes too long or escapes consistently fail because of movement, speed is a strong candidate. If you cannot maintain the collection or base state you want, inspect base improvements. If income itself is weak, compare pets before assuming a structural upgrade is the answer.

Write the problem in one sentence before spending: for example, movement is ending runs, or base management is interrupting income. After the change, ask whether that exact problem improved. If not, stop stacking the same upgrade and reassess. This prevents attractive labels from replacing evidence.

Know when speed deserves priority

Speed supports moving between bases, approaching opportunities, escaping with an egg, and responding to threats. It has broad value for active play, but it does not automatically make a poor route safe. Invest when movement is the limiting factor and pair training with route practice so the improvement changes real decisions.

Do not publish or rely on an exact breakpoint unless the current game exposes it clearly. Instead, test the same route before and after a training period. A meaningful improvement should be noticeable in travel, reaction, or escape consistency. If the route remains unsafe for other reasons, change the plan rather than chasing an unsupported target number.

Know when the base deserves priority

Base upgrades matter when your home loop constrains collection, income management, or defense. Read the current in-game description of an improvement and verify that the benefit exists before paying for it. The public guide intentionally avoids naming extra categories such as slots or offline earnings unless the correct game confirms them.

Evaluate a base change across a normal session. Did it reduce interruptions? Did it make your collection easier to manage? Did it help you return to the income loop faster? If the answer is unclear, another category may now be the bottleneck. Upgrade frameworks should adapt as the experience changes.

Keep a practical reserve

Spending every resource can leave you unable to act on a clearly better egg, pet, or newly visible improvement. Keeping a reserve is useful when upcoming choices are uncertain. The reserve does not need a fixed published amount; it needs a purpose, such as preserving your next strong comparison or avoiding a stalled loop.

On the other hand, an oversized reserve can delay an upgrade that would improve every cycle. Compare the repeated benefit with the opportunity you are protecting. If you cannot name the opportunity, the reserve may be habit rather than strategy. Revisit this decision whenever your collection or play style changes.

Audit the order after each update

A developer can rebalance costs, benefits, or progression paths without changing the high-level description. That means a static best-order list becomes stale quickly. Re-open each relevant interface after a visible update and verify that the choice still exists and still addresses the same bottleneck.

Use the update log on this site to see when official sources were checked, then use the current game to confirm balance-sensitive details. A transparent method survives change better than a copied list of prices. It also prevents data from another similarly named experience entering your decisions.
