释放精灵宝可本的进化力量！让你的精灵进化或变异成完全不同的形态。今天就开始你的旅程吧，让你的精灵变得不可阻挡！

### NFT的改变

在进化过程中，旧的NFT会被烧毁。如果成功，则会生成一个稀有度更高的精灵宝可本。这意味着旧的宝可本的等级、名称和技能将丢失。但是，由于等级和技能增加了精灵的战力，因此有助于增加成功进化的几率。

### 变异&#x20;

精灵在进化过程中有几率变异成另一种随机形态。

### 稀有度上限

拥有传说（或更高）稀有度的精灵不能参与进化，因为它们太强大了！

### 催化剂&#x20;

您可以添加EBEN作为催化剂，以增加进化成功的几率。&#x20;

*100%被用作催化剂的EBEN会被燃烧。*

### 概率计算

```
const base = 10**(rarity+1);
const success = (power/10) + catalysts;
const failure = (success > base * 8) ? (base * 2) : (base * 10 - success);
const evolution = canEvolve ? (success * 2 / 3) : 0;
const mutation = success - evolution;
const total = success + failure;

const chanceOfEvolution = evolution / total;
const chanceOfMutation = mutation / total;
const chanceOfFailure = failure / total;
```
