# How to level up cards
#### **If You Want to Grow the Strength of Your Cards, Here’s How!**
Once you claim a card, you unlock its potential to become even stronger. For example, after adding the **Snow Beast** to your collection by collecting its required shards, you can start **leveling it up** to gain an advantage over your opponents. Each level-up boosts the card’s stats, making it a key asset in building a powerful deck.
**Where to Find Cards to Level Up?**
Cards for upgrading your characters/chaampions/item/spell, like the **Snow Beast**, can be found in **Treasure Chests**. Open chests to discover **Cards**, **Diamonds**, and **Gold**—everything you need to strengthen your deck and dominate battles! Each chest offers unique rewards, with chances for high-tier resources.
**Why Upgrade?**\
\
Upgrading improves Strength , Health , and Power , making your card a more formidable force in battles.\
\
**Key Rules for Leveling Up Your Card**\
\
**Claim Before Upgrade:**\
Each card must be fully claimed (all required shards) before you can use shards to upgrade it.\
\
**Level-up cards:**
You can only use cards acquired from chests that match a specific character to level them up. For example, to level up the **Legendary Unicorn**, you need additional **Legendary Unicorn cards**—cards from other characters like the **Savage Barbarian** cannot be used.
