Ubisoft says Division 2 players who are "exploiting a bug" in the Descent game mode to gain "unfair amounts of XP" will be hit with two-week bans for their efforts, and could end up permanently banned if they persist in taking advantage of it.
The roguelike Descent mode went live in The Division 2 earlier this year, enabling 1-4 players to square off against multiple waves of enemies in a guns-blazing quest for skills, talents, and weapons. In the context of The Division's story, it's a training simulation for agents; in more practical gameplay terms, it serves as kind of a test bed for character builds because you begin the mode with no gear, perks, or specializations, and build out as you go.
