### **Boosts**

Boosts are multipliers that increase gem rewards from successful expeditions. They add **strategic depth** by letting players enhance returns at key moments.

* **In-Game Shop 24h Mining Boost (NFT):** 5% more Gems for 24h. Stackable with Lifetime Boost.
* **Giveaway 24h Mining Boost (NFT):** 5% more Gems for 24h. Stackable with Lifetime Boost and In-Game Shop Boost.
* **Lifetime Mining Boost:** Permanent 20% more Gems. Stackable with any 24h boost.

#### **Stacking Rules**

* Different boosts **can be combined**.
* The same boost **cannot stack with itself**.

**Example:**\
Lifetime (20%) + Shop 24h Mining Boost (5%) = 25% more Gems.
