Rituals is a skill practised by those skilled in the Magical arts. To cast rituals you must SKETCH shapes in the air (or SKETCH ALL to sketch all the shapes you know at once), wait for equilibrium, and then DANCE the appropriate ritual which is built up from the shapes. Ritual shapes can be sketched in most locations although protected environments (such as interior barracks, commodity sheds, inner sanctums of temples, etc) are restricted. Sketching technique is more subtle than first imagined; take heed!
Mages may type SKETCH for a list of shapes known to you. After the name of the ritual as specified in DANCE, you can name a city, a guild, or a specific individual that you wish the ritual to target. You can specify ENEMIES which would attack those who are not your friends. Mages can combine their might by sketching more shapes and dancing the rituals together. Thus together rituals of enormous power could be brought into being. Type UNDANCE (or UNDANCE followed by a specific ritual) to remove rituals of your creation or SENSE to sense rituals nearby.
