# KTTYs
### What is a KTTY?
At the heart of **KTTY World** are the **KTTYs -** an evolved species of mystical felines, uniquely gifted in **channeling mana**. Unlike ordinary creatures, KTTYs possess the ability to **adapt and grow**, drawing upon elemental forces and unique abilities to assist their Tamers in battle, exploration, and various life activities.
Each KTTY is a **lifelong companion**, forming bonds with its Tamer and developing over time through **training, exploration, and nurturing**. No two KTTYs are exactly alike, and through careful cultivation, Tamers can shape them into powerful allies suited to their preferred playstyle.
### Stats
Each KTTY in **KTTY World** comes with a unique set of stats that define its **abilities, strengths, and performance** in various gameplay scenarios. As KTTYs level up and grow closer to their Tamers, these stats can evolve, unlocking new potential in combat, life skills, and puzzle challenges.
**Core Stats:**
* **STR (Strength):** Influences physical power and melee-based abilities.
* **INT (Intelligence):** Affects magical prowess and energy-based skills.
* **AGI (Agility):** Determines speed, movement, and evasion.
* **DEX (Dexterity):** Enhances precision, critical chances, and gadget interactions.
**Status Stats:**
* **Hunger:** Indicates a KTTY's current energy and well-being. Keeping your KTTY fed ensures optimal performance.
* **Closeness:** Reflects the bond between Tamer and KTTY. A higher closeness stat improves responsiveness, unlocks passive bonuses, and may reveal special traits.
KTTY stats are influenced by **class type**, **level progression**, **equipment**, and **interactions** with the Tamer. With thoughtful care and training, each KTTY can grow into a powerful and loyal companion.
### **Costume Balls & Classes**
KTTYs are naturally versatile but can unlock specialized **classes and abilities** through the use of **Costume Balls**. When a Costume Ball is applied, a KTTY **transforms into a class-based variant**, gaining **new skills, traits, and playstyle adaptations**.
* **Example:** Applying a **Wizard-Type Costume Ball** transforms a KTTY into a **Wizard Class**, granting access to **arcane abilities like "Fireball"** or **mana-boosting passives**.
* KTTYs can **swap between different classes** by using new Costume Balls, encouraging experimentation and strategic team-building.
* Each class comes with **unique strengths**, influencing a KTTY’s **role in combat, puzzle-solving, or minigame performance**.
