Intuition defines ones sixth sense. An ability to deduce based off of pure feeling.

If you've ever just had a creeping feeling someone is around you, or that something bad may be up ahead, this is your Intuition kicking in. Without much intuition, one could be very dull. Only reacting at what's immediately in front of them. Fairly important for someone who cares for caution and preparation. Intuition could even be used for things that aren't an explicit threat, but sensing ones motive, or making an educated guess to substitute Knowledge.
