Chimera (Redux)

Legendary Resistance (2/Day). If the dragon fails a saving throw, it can choose to succeed instead.

Flying Pounce. If the chimera moves at least 15 feet straight toward a creature and then hits it with a bite or claws attack on the same turn, the target takes an extra 3 (1d6) bludgeoning or piercing damage (the same type as either the bite or claws); additionally that target must succeed on a DC 15 Strength saving throw or be knocked prone. If the target is prone, the chimera can make one bite attack against it as a bonus action.

Multiattack. The chimera makes three attacks: one with its bite, one with its horns, and one with its claws. When its fire breath is available, it can use the breath in place of its bite. 

Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) piercing damage.

Horns. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 11 (1d12 + 5) bludgeoning damage.

Claws. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) slashing damage.

Fire Breath (Recharge 5–6). The dragon head exhales fire in a 15-­-foot cone. Each creature in that area must make a DC 15 Dexterity saving throw, taking 31 (7d8) fire damage on a failed save, or half as much damage on a successful one.

Devastating Charge (Recharge 5-6). The Ram head lets out an odious bleat and the chimera charges an enemy. The Chimera moves in a straight line up to 30 feet, it may move through occupied spaces so long as it does not end its movement in an occupied space. Each creature whose space the Chimera moved through must make a DC 15 Dexterity saving throw, taking 17 (5d6) bludgeoning damage and is knocked prone on a failed save.

The Chimera can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Chimera regains spent legendary actions at the start of its turn.

Flight. the Chimera moves up to half its flying speed.

Attack. the Chimera makes a horns, claws, or bite attack.

Ram. the Chimera makes a shove attack. If the Chimera wins the contest the target is shoved 15 feet away, and is knocked prone.
