Reported — check current in game: Buy Fill Speed first when filling is slow, add Capacity when trips are too small, then add Token Multiplier once the loop is repeatable. Reported — check current in game: Delay Automation and niche upgrades until the core route is stable.
Quick Guide
Players want a clear first-buy order before wasting Tokens on upgrades that do not solve the current bottleneck.
- Upgrade the slowest repeated step first.
- Use Fill Speed when filling dominates the loop.
- Use Capacity when trips feel too small.
- Use Token Multiplier once cycles are already reliable.
Upgrade Route by Current Bottleneck
Use this as the default order, then adjust if your current bottleneck is obvious.
| Priority | Upgrade | Buy when | Why | Source status |
|---|---|---|---|---|
| Check | Fill Speed | Filling takes the longest | Compare the live node with other bottlenecks. | Needs current in-game check |
| 2 | Capacity | Trips feel too small | More value per run. | Context only |
| 3 | Token Multiplier | Loop is repeatable | Higher return from each drain. | Context only |
| 4 | Depth Unlock | Current route is stable | Access higher-value zones. | Context only |
| 5 | Automation | Active route is mature | Adds idle-friendly progress. | Reported — check current in game |
Fill Speed as a Possible Bottleneck
Fill Speed often wins early because it touches every run. A faster fill means more drains, more Tokens, and quicker access to the next upgrade.
When to Change the Order
Change the order when another bottleneck is clearly worse. If travel or capacity blocks progress, solve that before buying another speed level.

Drain the Lake Skill Tree Route — Choose by Current Bottleneck FAQ
What upgrade should I buy first?
Reported — check current in game: Fill Speed is the best first upgrade for most players because filling is usually the first repeated delay.
When should I buy Token Multiplier?
Buy Token Multiplier after the basic loop is fast and stable enough that higher payout per drain beats faster cycling.
