There are various upgrade systems available to defend the Kingdom from alien invasion.
Here are the ways to grow your Dice:

■ Merge
- Manual Merge: [Dice Camp] - [Tap the Dice to Merge] - [Merge]
- Automatic Merge: [Dice Camp] - [AUTO]
Merging is the most basic method to upgrade Dice.
You can merge the same Dice with an equal level.

■ Dice Upgrade (Dice Core)
- [Main Screen] > [Bottom left 'Growth'] > [Dice Upgrade] > [Tap the Core Icon to Upgrade]
You can enhance the core of your Dice by consuming Trait Stones obtained by clearing stages and minigames.
* Once you activate a core of a Dice, the core will be in effect for all the same Dice regardless of the level.
Ex) Level 1 Fire Dice and level 7 Fire Dice will all benefit once a Fire Dice Core is activated.

■ Research
- [Main Screen] > [Bottom left 'Growth'] > [Research] > [Tap the activated Research Stage]
You can gain special effects that enhance the overall field as you acquire and grow various Dice.
Enhanced buff values can be seen from the bottom right corner.

■ Dice Conversion
- [Main Screen] > [Bottom left 'Growth'] > [Exchange] > [Select a Dice and tap 'Exchange']
You can exchange one of your Dice level for another Dice level.
Dice Exchange is available from Legendary Dice level 7.
Dice can be exchanged for another Dice with the same type (trait).

Please note that the Dice used for exchange (material Dice) will disappear.
