Core mechanics
The Card system is a core progression feature that provides permanent, global boosts to your entire squad.
Global & permanent
Any stat boost gained from a card applies permanently to your entire squad.
Collection & upgrades
When you pull a card from a Card Pack for the first time, it is added to your deck. Subsequent duplicate pulls are added to the card's progression bar. Once you collect enough duplicates, you can level up the card.
Standard Card Packs
You can purchase standard packs using Diamonds:
- 1 Pull
100 Diamonds
- 10 Pulls
900 Diamonds
Card rarities & effects
As you upgrade cards, their designated stat percentages increase. However, all cards have a specific level threshold where their primary stat stops scaling, and they begin granting Damage instead.
