You can improve each hero's abilities in several ways:

🌀 Every ability has 10 levels, and you can upgrade them in the Hero Menu.

🌀 Each level increases the effectiveness of the ability. For example, if the ability inflicts damage, it will deal more damage when upgraded.

🌀 Upgrading requires a resource called nephrite. The rarer the hero, the more nephrite is needed for the upgrade.

You can obtain nephrite in three ways:

• Finding and using Nephrite Statues during expeditions.

• Completing levels in Elemental Dungeons.

• Purchasing nephrite from the Merchant’s Shop.
