Monster Hunter
Monster Hunter Level 1
Ranger
Classes: Ranger
You swiftly assess your prey and apply what you know. As part of the action used to Hunt your Prey, you can attempt a check to Recall Knowledge about your prey. When you critically succeed at identifying your hunted prey with Recall Knowledge, you note a weakness in the creature's defenses. You and allies you tell gain a +1 circumstance bonus to your next attack roll against that prey. You can give bonuses from Monster Hunter only once per day against a particular creature.
