In Cursed City's campaign, players will be able to upgrade their hero's abilities as they continue along. We get a look at some of them in this preview of the new Warhammer Quest box set, coming soon from Games Workshop.
From the article:
Warhammer Quest: Cursed City introduces a new mechanic that means your gang of heroes can become tougher and deadlier as you play through the game’s punishing campaign – and they were pretty nifty to start with! Even better, as your fighters level up, they don’t need to go through a training montage in order to pick up new skills. Join Qulathis the Exile as she gains the traits necessary to rid an entire city of its undead curse.
