Buy Fill Speed and Bucket Capacity first, then add Token Multiplier after the loop is stable. Public guide routes usually start with Fill Speed Lv 1, Fill Speed Lv 2, Bucket Capacity Lv 1, then balance speed, capacity, and Token Multiplier before Movement and deeper zones.

EarningsQuick Guide
Players need a real upgrade order they can follow, while exact costs and node text stay clearly marked by source.
- Start with Fill Speed Lv 1 and Fill Speed Lv 2.
- Add Bucket Capacity early so faster filling does not turn into too many short trips.
- Add Token Multiplier after the loop has enough speed and capacity.
- Use Movement Speed when travel becomes a real time loss.
- Buy Automation late, after active income is strong.
Skill Tree Families
Use these families as the upgrade map before spending tokens. The exact node text still needs in-game checks, but the practical order is speed first, capacity second, token value third, then movement, depth access, and automation.
| Family | Priority | Effect |
|---|---|---|
| Fill Speed | 1st | Faster bucket filling so every drain cycle starts moving sooner. |
| Capacity | 2nd | More water per trip, which keeps faster filling from turning into too many short runs. |
| Token Multiplier | 3rd | More tokens per drain once the basic fill and drain loop is stable. |
| Character | 4th | Movement speed and route comfort when walking time becomes a real loss. |
| Depth Unlock | 5th | Access deeper zones after your current loop can handle the next checkpoint. |
| Automation | Last | Passive token income after active earnings are already strong. |
First 15 upgrades
Use this as the opening build path to test. It prioritizes faster cycles, then bigger trips, then better payout value.
- Fill Speed is the first bottleneck in the public guide sourced route.
- Bucket Capacity becomes important once speed is no longer the only limiter.
- Token Multiplier starts after the loop has enough base output.
- Movement enters around the mid-route when walking time matters.
Checkpoint upgrade logic
Do not buy depth access if the current loop cannot handle the next zone. Shipwreck, Cavern, Mineshaft, Molten, Lost City, and Abyss each need stronger speed and capacity.
Automation timing
Automation is a late-game tool. Buy it after active loops produce enough tokens for offline value to matter.
Source boundary
Official sources confirm Skill Tree existence and completion. Upgrade order, cost scaling, and node values remain public guide sourced until checked in-game.
