Although I'm biblically not allowed to perform any acts of divination, I still occasionally do.

I continuously wear a cat's bell on a leather cord around my neck - reminder that all actions have consequences (and also a measure of energy expenditure, as well as a spontaneous notification if I'm late for class, plus a few other things).

Anywho - I use it as a pendulum any time I need information. Quite useful for general information gathering. Is someone going to be there tonight? Is the item I seek in this room? So far, pretty accurate. Just not allowed.
