Another thing to be noted about the card system in Lost Ark is that each card has the designation of an "Awakening Level" toLost Ark Gold it, which is indicated through the amount of gemstones on the bottom inside the cards.
The card begins at level 0 . It can progress up to the level 5. It can unlock additional sets of bonuses and effects after it level's up.
To upgrade your card into the new Awakening Level, you need to complete two steps. The first is to boost its XP gauge by feeding it XP cards or duplicate cards.
Continue to do that until its XP indicator grows. After that you will need to provide it with additional duplicate cards to "Awaken" to it (push it up and up to the next one).
The more advanced the Awakening Level the more duplicate cards you'll require to make it to an even higher level. The duplicate cards needed by every Awakening Level are listed below.
