# 🛠️ Durability & Maintenance

Durability is the hidden cost of earning in Gear Runner.

### How Durability Works

* Every unit of energy used causes durability loss
* Efficiency remains optimal above a durability threshold
* Below this threshold, performance declines gradually
* At zero durability, gear stops generating rewards

### Player Decisions:

* Repair early for efficiency
* Delay repair to save resources
* Replace gear instead of repairing

Durability ensures that rewards are always paired with responsibility.
