Levelling cards is the primary way of making them stronger, improving their defensive and offensive ability, and helping you clear more difficult quests. While cards naturally gain experience through questing, it’s much faster to directly feed them experience through items.
In-universe, various pyroxene minerals are the essence of magic and power most of the magical world. The same pyroxenes, along with its powdered forms, are used level up your cards. There are three tiers of levelling items that you will find in your journey:
 |
 |
 |
|---|---|---|
| Common pyrosand | Pure pyrosand | Pure pyroxene |
| 10 experience | 50 experience | 300 experience |
| (= 5 common pyrosand) | (= 6 pure pyrosand) |
The maximum level of a card is influenced by your player level and by the card’s
star ranking. An individual
card’s maximum level is determined by 20 ✕ (star rank + 1) (i.e., 20 for star
rank 0, 40 for star rank 1, …). Your player level determines the maximum
level for all your cards, and is determined by 5 ✕ ((player level ÷ 5) + 1)
(i.e., 5 at player level 1, 10 at player level 5, 15 at player level 10, …). A
card’s effective level cap is the lower of both of these numbers; for example, a
card at star rank 2 and player level 40 can only reach level 45, but a star rank
1 card can reach its (relative) full potential of level 40.
