Upgrades
Upgrade your buildings to increase their Yield Points. Each upgrade level costs FUEL and rolls for a YP value within a defined range.
How Upgrades Work
Any building can be upgraded from level 0 up to level 10. Each upgrade costs a fixed amount of FUEL and assigns a new YP value by rolling within the range for that level. Higher levels have higher costs but also higher potential YP.
Upgrade Costs & YP Ranges
| Level | FUEL Cost | YP Range |
|---|---|---|
| 0 | — | Base |
| 1 | $0.50 | 5–10 |
| 2 | $1.00 | 10–18 |
| 3 | $2.00 | 18–30 |
| 4 | $4.00 | 30–48 |
| 5 | $8.00 | 48–75 |
| 6 | $16.00 | 75–115 |
| 7 | $32.00 | 115–170 |
| 8 | $64.00 | 170–250 |
| 9 | $128.00 | 250–370 |
Knowledge Bonus
Owning Knowledge-chain buildings adds bonus YP to every upgrade roll. Each Knowledge building contributes +2 YP to the roll result, up to a maximum bonus of +20 YP. This bonus is applied after the random roll.
Ascension Traits (Level 10)
Reaching level 10 is a special milestone called Ascension. Ascended buildings receive a unique trait that provides an additional permanent bonus. Ascension traits are randomly assigned and vary by building chain.
