![Evoskulls Genesis](https://3737230276-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLSj2qVEeJkYKzq8LFl8s%2Fuploads%2FJswpepiCHxV0obrkKcvS%2FwhatareEvo.jpg?alt=media\&token=ccead1f4-f4e4-477e-bc47-3e60fe27c30b)

**EvoSkulls** are a collection of **Unique, Animated, 1/1 NFTs** on the Cronos blockchain. The collection consists of 333 **Super-rare Skulls, all 1/1.**

Each EvoSkull has a **custom made unique animation**, body, hat, face and outfit. They are all handmade by our mad and beloved Dr. Jiko.

## **How do I get an EvoSkull?**

**EvoSkull** as suggest the name is the evolution of a normal [**CroSkull**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-croskulls)**.** This process is done through using your [CroSkull](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-croskulls) as well as a <mark style="color:purple;">**Purple Potion**</mark> together.

<mark style="color:purple;">**Purple Potion**</mark> can be obtain by merging <mark style="color:blue;">**1 Blue**</mark> and <mark style="color:red;">**1 Red**</mark> potion inside the Laboratory section of the [Dapp](https://app.croskull.com/#/laboratory). Here're some useful details about Potions:

* The <mark style="color:blue;">**Blue**</mark>, <mark style="color:red;">**Red**</mark> potion had a total supply of 333 each, which could be merged together into a <mark style="color:purple;">**Purple**</mark> potions. The potions are burned upon use.
* <mark style="color:blue;">**Blue**</mark> and <mark style="color:red;">**Red**</mark> potions were airdropped for **free** to the CroSkulls Holders

<br>

By setting the <mark style="color:purple;">**Purple Potion**</mark> on fire on a **CroSkull**, you will be able to summon a powerful and rare [**EvoSkull**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls). In the process, the purple potion is burned while the [**CroSkull**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-croskulls) NFT does not, so you get to keep it after the process!

## What can EvoSkulls do?

![](https://3737230276-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLSj2qVEeJkYKzq8LFl8s%2Fuploads%2FWDrCGBqTOPbkA3LPZc0C%2Fevo_scheda.jpg?alt=media\&token=5ad63fbb-de68-425d-9220-3f1b04c814ab)

An [**EvoSkull**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) generates more [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve/earning-usdgrve#what-can-i-do-with-usdgrave) than a [**CroSkull**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-croskulls). [**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) can claim **9 $GRVE** daily. These are not compounded over multiple days, so it's important to claim everyday. (Any unclaimed [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve) is burned at the end of each season).

{% hint style="info" %}
Remember to claim everyday to increase your Grave yield!
{% endhint %}

They also have on-chain stats, which gives them the ability to do missions. These are only the [**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) and [**pets**](https://croskulls-organization.gitbook.io/croskull/ecosystem/pets) that can do.

[**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) stores their stats on-chain, this means that these data can be used by our smart contracts for the mission systems and future player vs player activities.

### EvoSkulls On-Chain Stats

When summoned, every [**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) starts with all stats equal to 5, except the Charisma, that will be a random value between 0 an 4.&#x20;

Stats are required to participate in the Missions. [**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) generally have higher stats than the pets. These stats can be affected by **Malus** after missions/battles, which can temporarily reduce them until cured for the **Malus**.

### EvoSkulls Grades

[**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) Grade is based on the total power value. This power is the sum of all the stat numbers combined.

Since the Grade is calculated based on the total power, if your [EvoSkull](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) has <mark style="color:purple;">**Sad Malus**</mark>, the final grade is directly affected. Decreasing the total power and possibly grade as well.

**EvoSkulls can be have 4 differents Grades:**&#x20;

| GRADE NAME                                | POWER NEEDED |
| ----------------------------------------- | ------------ |
| <mark style="color:green;">**B**</mark>   | 28 to 50     |
| <mark style="color:red;">**A**</mark>     | 51 to 70     |
| <mark style="color:yellow;">**S**</mark>  | 71 to 85     |
| <mark style="color:purple;">**S+**</mark> | 86 to 90     |

### &#x20;EvoSkull Level System

Every [**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) start from level 0 when they are summoned. Through the use of [$SLS](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/souls-usdsls) or sending you [EvoSkulls](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) on missions you can increase their experience points. Once you have reached the needed amount of experience points for your level, you can level up your [EvoSkull](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) using the level up requirement cost for that level with [$RUDE.](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/rude-usdrude) &#x20;

Each level requires higher amount of both [$SLS](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/souls-usdsls)  and [$RUDE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/rude-usdrude), meaning leveling up will get more challenging each level!\
\
Your [**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) stats affect the outcome of **battles** and allow you to do missions, raids (coming in the future) and dungeons (coming in the future) where the more difficult missions gives you higher rewards, but also requires higher stats and level to accomplish.

### EvoSkull Stamina System

When [**EvoSkulls**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) are summoned, they start with 10 Max Stamina. Each time you upgrade your [**EvoSkull**](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls), the max stamina will increase by **1 point.** (es: Level 5 Evo has 10 + 5 = 15 max Stamina).

Every **PVP Battle** or **Mission** will require and consume **1 Stamina**, plus during the PVP battles, 1 of the **2 players** can receive a **Malus**, if your skull is affected by "**Hungry**" Malus, max stamina will remain the same but the **current available stamina** will be decreased by 5. If current (available) stamina is lower or equal to 5, stamina will become 0.

Every 2400 blocks (currently roughly equal to 4 hours ) a stamina block is automatically restored, this restore is cumulative, so if you wait until 24000 blocks (40 hours) have passed, you can estimate that 10 stamina points have been restored.

To perform PVP (battles) or PVE (missions):

* Current stamina must be equal or greater than 1,
* Current block must be greater than the evo unfreeze block

{% hint style="info" %}
Ex: EvoSkull at level 5 with 15 max stamina and current stamina to **7**, if affected by **Hungry** the current stamina will be  7 - 5 = 2.
