# Core Crystals

The heart of battle in PlayerOne. In the vast world of PlayerOne, Crystal Cores are not only the core of the player's character, they are also the protagonists of every adventure story. Each Crystal Core carries a specific elemental attribute - water, fire or ice - which not only defines their combat characteristics, but also forms the cornerstone of the entire game combat.

## **Character Attributes**

* **Warrior**\
  As a solid shield on the front lines, warriors have high health and attack strength. They have medium defense and slow attack speed, suitable for close combat.
* **Knight**\
  Knights possess the strongest defense on the battlefield, moderate attack power, medium attack speed, and lower health, allowing them to fight at mid-range.
* **Mage**\
  Mages have the fastest attack speed and moderate health. Due to their low attack power and defense, they are best suited for ranged attacks. Additionally, each class has three different elemental attributes: ice, fire, and water.

## **Character Breakthrough**

After reaching the level cap, characters can break through this limit by collecting specific materials, thus continuing to increase their level and capabilities. Breaking through not only enhances a character's basic attributes but also strengthens their existing skills.

## **Rarity**

The rarity of characters ranges from 1 star to 5 stars, with higher-starred characters typically having stronger base abilities.

## **Elemental Counters**

Each class has three elemental attributes: water, fire, and ice.There are counter relationships among these elements, such as:

* **Fiery Ice Shatter**\
  A reaction between fire and ice elements. When a fire attribute character attacks an ice attribute enemy, it can significantly enhance the attack power and reduce the enemy's defense.
* **Frost Seal**\
  An interaction between ice and water elements. When an ice attribute character attacks a water attribute enemy, it boosts physical attack while greatly reducing the water attribute enemy's defense, making them more susceptible to damage.
* **Water-Fire Rupture**\
  A strong interaction between water and fire elements. When a water attribute character faces a fire attribute enemy, the attack power is enhanced, and the enemy's defense is lowered, causing substantial damage.

## **Team Formation**

Players can freely form teams based on the elemental attributes of their characters. Combining different elemental attributes can trigger powerful combo techniques, boosting the overall combat power of the team. Each team can consist of up to three characters, and a strategic team configuration can maximize advantages against various enemies.
