you learn how to search for your enemy's weakness and shatter points. You gain the following benefits:

• Increase your Wisdom score by 1, to a maximum of 20.

• You gain proficiency in the Perception or Deception skill. If you are already proficient in the skill, you add double your proficiency bonus to checks you make with it.

• When you take the Attack action on your turn, you can replace one attack with a perception check on the enemy. if he tries to hide his weakness, he uses his reaction and roll stealth check against your perception, if he doesn't try to hide it then the DC is his armor class. if you succussed on the check, you learn one of his weaknesses, one fact about him, all his damage and conditions immunity, resistance and vulnerabilities, his creature's type and you have advantage on all attack rolls against him until the end of your next turn. you can do this ability only ones per enemy.

• When you take the Attack action on your turn, you can replace one attack with an attempt to deceive one humanoid you can see within 30 feet of you that can see and hear you. Make a Charisma (Deception) check contested by the target's Wisdom (Insight) check. If your check succeeds, your movement doesn't provoke opportunity attacks from the target and your attack rolls against it have advantage; both benefits last until the end of your next turn or until you use this ability on a different target. If your check fails, the target can't be deceived by you in this way for 1 hour.
