When the GM Rolls

Normally, the player rolls dice for his own character. There are two exceptions:

First, in a situation in which the character shouldnJt be able to tell whether he has succeeded I especially when he is trying to get information I the GM rolls in secret. If the roll succeeds, the GM gives the player true information. If the roll fails, the GM lies or gives no information at all.

Second, in a situation in which the player simply shouldnJt know what's going on. This includes most lsenseL rolls. The GM should simply roll in secret and inform the player of any consequences that his character would be aware of.
