NAME
destruct - destruct an objectSYNTAX
destruct [-f]DESCRIPTION
If there is an object named "object" in the same room, it can be destroyed with 'destruct object'. If it is a cloned object, the original blue print (the master object) will still remain loaded. If it is a singular object (not cloned), like a castle, then all data about the object will be discared. An 'update' of a castle will have the same effect. This command will respect the dangerlevel settings of your wizmod. Flags: -f Ignore the dangerlevel setting.NOTE
Never 'destruct' a player.
