Description
Your extensive knowledge of monstrous bestiaries grants you special insight into their strengths and weaknesses. If you spend a round consulting your texts, you may use this stance to yield a GM advantage that reveals the monster's mechanical weaknesses (such as vulnerability to fire, natural cowardice, poisoned flesh, etc). If such a weakness is a legendarily guarded secret or known to no one, you must study the monster directly to reveal its weaknesses, and the GM may require a relevant check.
