Arena Chimera

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

Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 11 (3d6 + 4) piercing damage.

Horns. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 10 (3d12 + 4) bludgeoning damage.

Claws. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage.

Deadly Leap (Recharge 3-4). The chimera jumps at least 15 feet as part of its movement, it can use its action to land in a space, that contains one creature. This creature must succeed on a DC 18 Strength or Dexterity saving throw or be knocked prone and take 2d8 + 5 slashing damage. On a successful save, the creature isn't knocked prone and is pushed 5 ft out of the chimera's space into an unoccupied space of the creature's choice. If no unoccupied space is within range, the creature instead falls prone in the chimera's space.

Fire Breath (Recharge 5–6). The dragon head exhales fire in a 15-­-foot cone. Each creature in that area must make a DC 18 Dexterity saving throw, taking 5d8 fire damage on a failed save, or half as much damage on a successful one.

In place of a claw or head-butt attack, the Chimera can cast:

Fireball or Poison Spray and be poisoned for 1d8 rounds when Poison Spray is used.

The Chimera can only use these two features once.
