The trance command may only be used by sorcerers, mystics and clerics. When
you enter into a trance, you are making your psychic powers available to
the other players in your immediate location. I.E. if you have a psychic
ability stat of 100 and your partner also has a psychic ability stat of
100, when you enter into a trance your partner will be able to cast spells
as if his psychic ability were 200.

The trance is extremely tenuous - ANYTHING you type at the keyboard will
cause you to break concentration and exit from your trance.

If you are trancing in a room, you will receive experience towards a psy
quest if others in the room are using magic to kill monsters (thus 
benefiting from the use of your psy).
