Acutomancy

Acutomancy is a divination method involving sharp objects.

Here is an example:

~removes three fine steel daggers from her bag~

The direction of the blade determines if it is a yin, or a yang
line. If a dagger is pointing up or down, I consider it yin.
If a dagger is pointing left or right, I consider it yang.

~drops the first dagger on the ground~
--> ------
~drops the second dagger on the ground~
<-- ------
~drops the third dagger on the ground~
