Arch Griffon

Keen Sight. The griffon has advantage on Wisdom (Perception) checks that rely on sight.

Multiattack. The griffon makes two attacks: one with its beak and one with its claws.

Beak. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 9 (1d10+ 4) piercing damage.

Claws. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage.

Acid Spit. Ranged Weapon Attack: +7 to hit, reach 15 ft., one creature. Hit: 3 (1d6 + 3); bludgeoning damage, the target then suffers acid damage for one minute.

Screech (Recharge 4-5). The griffon makes a terrible screech. Each creature that is within 40 feet of the griffon must succeed on a DC 15 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw t the end of each of it's turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the griffon's Screech for the next 24 hours.
