Beastial Instincts. The chimera has advantage on saving throws against any spell that targets only the chimera (not an area) that it can see. 

Three Heads. The Chimera has advantage on Wisdom (Perception) checks and on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious.

Wakeful. When two of the Chimera’s heads are asleep, their other head is awake.

Forest's Grace. The chimera doesn’t provoke an opportunity attack when it flies out of an enemy’s reach.

Talons. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 10 (1d8+5) slashing damage.

Ravenous Jaws. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (1d12+5) piercing damage. and a creature needs to make a DC 14 constitution saving throw on a fail the chimera regains the amount of damage dealt in hit points.

Hit: 11 (2d6+5) piercing damage. and a creature of medium or smaller size needs to make a DC 15 Strength saving throw or become restrained and grappled on a failure. a creature that is grappled in this way can at the start of its next turn make the save. on success, a creature is not restrained and grappled. 

Deathly Roar (Recharge 6). The chimera roars a wave of necrotic energy in a 20-foot radius sphere centered on itself. Each creature in that area must make a DC 14 Constitution saving throw, taking 20 (3d12) necrotic damage and become frightened of the creature until the end of the creatures next turn on a failed save, or half as much damage on a successful one and a creature is not frightened.
