# Rarity Collection

In RealGo, each Meme IP offers a diverse range of pets with varying levels of rarity, ensuring that every collector has a unique and exciting journey. The rarity levels are categorized into SSR, S, A and B.

**Rarity and Attributes**

Pets with higher rarity levels, such as SSR and S, come with significantly higher attribute values, making them more powerful in battles. These attributes include:

* **Defense Power (DEF):** Reduces incoming damage from enemies.
* **Attack(ATK)**: Determines the strength of normal attacks.
* **Health Points (HP):** Represents the pet's survivability during battles.
* **Focus (FOC):** Influences energy recovery, skill charge rate, and skill cooldown.
* **Speed (SPD):**Determines the cooldown time when switching pets. Higher Speed reduces the switching cooldown.

**Rarity and Capture Rates** 

The rarity of a pet directly impacts its capture rate. The rarer the pet, the more challenging it is to capture and the less frequently it appears. This adds an element of excitement and challenge to the collecting experience, as players strive to track down these elusive high-rarity pets.

**Rarity and Star Level Upgrades**

Upgrading a pet's star level is a crucial step in unlocking its full potential. However, the process becomes more complex and resource-intensive as the rarity increases. For instance, SSR pets require a greater number and variety of shards compared to their lower-rarity counterparts.
