Cunning

Ever hear of a villain in a story who was "cunning?" This means that person could react quickly to events, seized opportunities, and could decipher how to plot and scheme and make things work.

This helps in aiming attacks during combat. Cunning can be used for hearing, seeing, or finding what others might not. On the flip side, cunning characters know all the good hiding places.

A character with a poor Cunning score is oblivious, easily-surprised, and has to stare at those 3D optical illusions for hours. A character with a good Cunning score is a cognitive master who can identify important minutia at a glance, eavesdrop on distant conversations, and never loses his car keys.

Iago from Othello is one of the most cunning characters ever. Also numbered among the cunning are The Wolf from Little Red Riding Hood, The Devil, Loki, and lawyers.
