# Evolve

### Evolve Feature

Evolve is a feature that helps players increase one Green Hero’s Rarity with materials: additional Green Hero(es), Evolve Stone, $GFRUIT, and $GRBE.

### Evolve Stone

Evolve Stone is a new NFT Item that will be used as material to evolve Green Hero. 

To evolve a Green Hero, it is required to have an Evolve Stone with the same or higher Rarity than the Green Hero’s next Rarity grade.

*Example: To evolve a Rare Green Heroin to an Epic Green Hero, only Evolve Stone with Rarity of Epic, Legendary, or Mythical is qualified.*

**Note:** After the Evolve feature is released, the NFT Item - Training House will be replaced by Evolve Stone.

*  Players will receive Evolve Stone Fragments in PvE instead of Training House Fragments.
* All the existing Training House Fragments will be converted to Evolve Stone Fragments in a 1:1 ratio Evolve Stone has its own Rarity. 

### Mechanism

**Requirements:** 

* 01 main Green Hero 
* 1-3 additional Green Hero(es) used as material. 
* 01 Evolve Stone has the least Rarity equal to the Green Hero’s next Rarity grade.

*Example: Only Epic/ Legendary/ Mythical Evolve Stone is qualified to evolve a Rare Green Hero into an Epic Green Hero. $GFRUIT $GRBE.*

#### How to calculate the success rate of "Evolve"

Each Rarity in Evolve requires a specific amount of points and each additional Green Hero will provide points to increase Evolve’s success rate. If the required points are reached, Evolve is guaranteed success.

**In case of success** ✅

* The Rarity of the main Green Hero increases by one grade. 
* Green Hero’s Level and Body part Level remain the same. 

**In case of failure ❌** 

• Main Green Hero remains the same

 **📌 Note:** All the "material" Green Hero(es), Evolve Stone will be **burned** whether you succeed or failed to Evolve.

**Example:** The Rarity of the main Green Hero before Evolve is Rare. Required points to Evolve from Rare to Epic to 27. A player uses 1 Uncommon Green Hero and 1 Rare Green Hero as material.

\=> Total points provided by “material” Green Heroes = 3 \* 1 + 9 \* 1 = 12 

Success rate = 12 / 27 = 44 % => The main Green Hero has a 44% chance of evolving to the next Rarity grade
