INVIS

This command controls how you want to exorcise your innate invisiblity Power. All immortals have the ability to become invisible to weaker beings on the mud.

If an optional level parameter is given, you are telling the mud to make you invisible to anything below that level. Note that you cannot specify a level higher than your current level.

If no parameter is given, this command toggles your invisibility on and off, defaulting to an invisibility setting of the lowest level of immortal.
