Upgrade Your Mercenary: how it worked

Complete a Mercenary Challenge node in a dungeon to earn upgrade marks. Earn 2 marks and pay the mercenary’s fee to upgrade them permanently for your account.

Dungeon encounters can now be marked as a Mercenary Challenge. Defeating that encounter with a Mercenary will award bonus gold and grant progress towards upgrading that Mercenary.

The game's own words. The fee was set by the game's server, so its amount isn't in the game files. A mercenary could be upgraded once.

Party passive

At the start of the game, two random troops in your deck get "Deploy - Create a Valor and put it into your hand."
