The GW2 Wiki’s abbreviations page is extremely useful. However, sometimes they are missing terms we think players might find useful.
- CM
CM, or Challenge Mode, is a type of content that takes standard modes and makes them more difficult. This can be through introducing time limits, adding or changing mechanics, or otherwise modifying encounters. Not every content has CM modes. Some T4 fractals, raids, and strikes have CM modes. The difficulty of CMs varies greatly by encounter.
