# Purple Stage

The Purple Stage unlocks after clearing the Blue Stage, offering players a more challenging and rewarding gameplay experience. Assemble your 4-person team, defeat powerful monsters, and earn valuable resources as you progress through this advanced level.

**Entry Requirements:**

* Access to the Purple Stage requires unlocking specific Holy Armor NFTs, which serve as the initial consumption threshold for this stage.
* Ensure your team is adequately prepared to tackle the higher difficulty level.

**Rewards:**

* **Enhanced outputs compared to the Blue Stage, including:**
  * Increased $RST production.
  * Rare drops such as hero fragments for hero upgrades and development.
* **Output Efficiency:** The quality of your heroes directly influences reward probabilities:
  * Higher-quality heroes yield better chances for valuable resource drops, including $RST.

**Hero Vitality Mechanics:**

* **Vitality Consumption:** Each battle consumes hero vitality, which impacts performance and output bonuses.
* Heroes with depleted vitality can still participate in battles but will no longer contribute to additional output probability bonuses.
