Anatomy
Knowledge of the anatomy of other creatures is a great boon to fighting classes. With a brief appraisal of a person or creature someone skilled in anatomy is able to make an accurate judgement about their strength and health. The skilled anatomist is also able to target attacks with melee weapons to more critical parts of a foe's physiology, and thereby do more damage to them.
Fighters and rogues have the greatest potential to learn anatomy, rangers may study it to a competent degree.
Active Uses: Allows you to determine the strength of a creature.
Passive Attributes: Improves the chances of critical hits in melee combat.
