Keen Sight The gryphon has Advantage on Wisdom (Perception) checks that rely on sight.
Tactical Assessment A number of times per day equal to the gryphon's CR, it can choose to switch its initiative with the creature who has the lowest initiative roll. If it does so its next attack action will be an automatic hit (although the player may still roll for critical hits).
Weak Spot A number of times per day equal to the gryphon's CR, using a Bonus Action, the gryphon can concentrate on a single target, looking for the best place to strike. The first attack the gryphon makes on that target each turn takes an extra 1d6 1d6 damage of the attack's type and the gryphon can't take opportunity attacks from that creature. If the target the gryphon is concentrating on dies or becomes unconcious you can use a Bonus Action on your next turn to begin concrentrating on another creature without counting towards your total daily uses.
