# Gem Upgrade

Upgrade Gems in the Upgrade tab by burning GST and combining 3 same-level, same-type Gems into a higher-level Gem. From Level 4, GMT is required for upgrades.

**Note:**

* **Gem upgrades can fail at lower levels, resulting in lost Gems.**
* **Gems are in-app asset and cannot be transferred to Wallet.**

**Warning**: Gem upgrades from Level 1 to 5 have a failure risk. Should an upgrade attempt fail, the player will lose the GMT, GST, and Gems that they used.

**Awakening Effect:** Enhances Sneaker's Base Attribute. For example, a Level 2 Efficiency Gem boosts a Level 0 Sneaker with base Efficiency of 5 to a total of 15, factoring in both the gem's Attribute and its awakening effect.
