Syaoran's Lasin Board
This is Syaoran's most useful magical tool. He can use it to do a number of
things. It was when he used it to do a fortunetelling that he discovered the
release of the Clow Cards.
The board can also be used to pinpoint the location of a Clow Card. When
used in this manner, the board will emit a thin blue laser like light that
aims directly towards a nearby Clow Card.
There are eight points to this board and I'm going to hazard a guess that
they relate somehow to the Chinese philosophy of the I Ching. But you'd
have to ask someone who knows more about reading Chinese to confirm that.
