A large part of the original intent for "Discworld MUD" was to move away from a restrictive class system, and to allow a player to do (almost) anything with enough effort and advancement. Each character can join one of a selection of guilds, a combination of class and in-game organisation, and each guild has several unique abilities not shared with any other. Many mundane attributes such as hit points, perceptiveness, and swimming skill are not affected by choice of guild. While players can advance and benefit from any skill, players get extra bonuses and abilities within the skill set of their guild.
