Increase your Intelligence score by 1, to a maximum o f 20.
Whenever you perform a History check to recall knowledge, you can attempt a DC 20 History check to recall known weaknesses of a creature within sight. If you succeed, you notice a weakness and gain the following benefits:
- You gain a +1 bonus to attack rolls and can immediately convey this information to your allies as part of the check. Each ally gains a +1 bonus to their next attack roll against the creature, as long as their attack is made before the beginning of your next turn.
- On your turn, you can use your reaction to assume a parrying stance. Doing so grants you a +1 bonus to your AC until the start of your next turn.
- If you make an opportunity attack against this creature, you have advantage on the attack roll.
