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.
Three Headed
Any ability that would sever one of the three-headed goat's heads (such as a critical hit with a vorpal weapon) severs one head at random. Losing a head doesn't kill the three-headed goat (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.
Triple Opportunity
The three-headed goat eidolon 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.
Melee Saanen Goat Bite +14, Damage 1d6 fire plus 1d8+6 bludgeoning
Melee Hoof +14 (agile), Damage 1d6+6 bludgeoning
Melee Boer Goat Bite +14, Damage 1d6 sonic plus 1d8+6 bludgeoning
Breath Weapon(arcane)
The two-headed goat breathes a 20-foot cone that deals 3d6 damage to all creatures in the area (DC 18 basic save of a type indicated below).
The two-headed goat can't use either of its Breath Weapons again for 1d4 rounds.
Boer Cone of 3d6 sonic (DC 18 basic Will)
Markhor Cone of 3d6 poison (DC 18 basic Fortitude)
Saanen Cone of 3d6 fire (DC 18 basic Reflex)
Elemental Bite
Each head deals an extra 1d6 damage of a type matching the head's breath weapon.
Three-Headed Strike
Frequency once per turn
Effect The three-headed goat makes a Strike with each of its heads, each at a –2 penalty and targeting a different creature. These Strikes count as two attacks for the three-headed goat's multiple attack penalty, and the penalty doesn't increase until after it has made all three attacks
