# 升级 & 修复建筑

### Upgrading Buildings

Utility Buildings are upgradeable, and cost $CHEDDAR and Building Upgrade Points to upgrade. By upgrading, the owner is able to increase some of the underlying parameters of his or her buildings:

* **HQ Building**
  * Upgrades allow owner to upgrade other buildings to higher levels
* **Refinery**
  * Upgrades increase refinery speed and throughput, and improves the refinery yield
* **Enriched Orb Storage**
  * Upgrades increase storage capacity
* **Mine**
  * Upgrades provide a drop probability modifier and increase the chances of higher tier Engram Fragments being dropped
  * Upgrades also improve the mining yield
* **Engram Fragment Storage**
  * Upgrades increase Engram Fragment storage capacity

Note: Only the Land Owner can build or upgrade buildings.

### Repairing Buildings

Defensive buildings, like Walls, require repair after taking damage. Repair requires the following:

* **Cost**: X $CHEDDAR \* Inflation Coefficient
* **Repair Time**: 3 hours (level 1)

Once repaired, the HP and Defensive Power of the building goes back to 100%.

Note: All $CHEDDAR collected for upgrading or repairing buildings (and speeding up progress) goes to the Game DAO. The Game DAO burns all of the $CHEDDAR that it receives, unless otherwise decided by the governance token holders.
