About this game
Climb from rookie knight to legend across four difficulties and an endless Nightmare mode. Build your own path through a massive skill tree, dispatch expeditions while you play, hunt gear up to infinite Godly rarity, and craft the exact bonuses you want. The climbing never really stops.
