Mastery is a game mode designed to challenge players by imposing certain restrictions. Each map has a specific set of 5 challenges to complete. Mastery mode also restricts your gear, stats, and Ascension according to the Chaos tier you are playing. Any mods you have on your gear will be set to the Chaos tier of the map you are playing, even if those mods were originally a lower tier.
