Mist Knight Ark Pass[]

Complete missions to progress through 30 Ark Pass levels for new rewards.

The regular Ark Pass is free and grants a variety of helpful rewards, such as Pheons, honing material selection chests, and card packs! Ark Pass progress is earned across your entire roster, while the rewards are roster bound.

Those interested in more rewards and cosmetics can exchange Royal Crystals for two premium reward tracks (Premium and Super Premium), which each layer in additional rewards to the leveling track. The Premium Ark Pass adds rewards at all 30 levels earned alongside the free rewards. Examples include more honing material selection chests, battle items, and more! On top of the Regular and Premium rewards, the Super Premium Ark Pass weaves the Mist Knight skins, Fluffy cat mount and pet, and a Legendary Card Pack through the Ark Pass.
