Exact Skill Tree prices are not publicly verified. The list ranks upgrade categories by confirmed gameplay role rather than fabricated prices.

Ranking criteria

Reduces repeated trips

Improves tokens per minute

Unlocks deeper progression

Helps phone recovery

Keeps the loop comfortable for daily play

Trip reduction

More capacity means fewer returns to the drain point and a smoother token loop.

Upgrade rule: Prioritize when you are returning too often with small loads.

Faster fills

Fill speed raises token income immediately because every loop starts with collecting water.

Upgrade rule: Prioritize when filling the bucket is slower than travelling or draining.

Income scaling

Better token conversion compounds with every future run once the basic route is comfortable.

Upgrade rule: Invest after capacity and fill speed stop feeling like bottlenecks.

Area unlock

Depth upgrades matter when your current loop can fund deeper attempts without stalling.

Upgrade rule: Buy before exploring deeper sections or chasing phone-related milestones.

Quality of life

Movement and convenience upgrades are useful, but they should not delay core token growth early.

Upgrade rule: Add when long routes are causing wasted time.
