Oversized Chimera

Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using. Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.

Any ability that would sever a chimera's head (such as a critical hit with a Vorpal Weapon ) severs one head at random. Losing a head doesn't kill a chimera (as long as it has one head left), but it does prevent it from making Strikes with the lost head or using the head's Breath Weapon.

A oversized chimera gains 2 extra reactions each round that it can use only to make Attacks of Opportunity. It must use a different head for each reaction, and it can't use more than one on the same triggering action. If it loses one of its heads, it also loses one of these extra reactions.

The oversized chimera breathes a 30-foot cone of fire that deals 13d6 fire damage to all creatures in the area (DC 32 reflex save). The chimera can't use Breath Weapon again for 1d4 rounds.

An oversized chimera's dragon head deals an extra 3d6 fire damage (already included) .

The oversized chimera makes a Strike with its dragon jaws, lion jaws, and goat horns, each at a -2 penalty and targeting a different creature. These Strikes count as only one attack for the chimera's multiple attack penalty, and the penalty doesn't increase until after it has made all three attacks.
