Combat

Breath Weapon (Su): Once every 5 rounds, an ibrandlin can breathe a 30-foot cone of fire that deals 2d6 points of fire damage to every creature it touches. Affected characters who make a successful Reflex save (DC 21) take half damage. An ibrandlin can use its breath weapon and its claw attacks in the same round by using a full attack action. In this case, the creature forfeits its bite attack in favor of the breath weapon.

Pin (Ex): An ibrandlin can jump and land on opponents as a standard action, using its whole body to attack. A pin attack is effective only against Medium-size or smaller opponents. An ibrandlin can pin as many creatures as will fit under its body (a 10-ft.-by-30-ft area). Creatures in the affected area must toll successful Reflex saves (DC 21) or be pinned under the ibrandlin. The ibrandlin can choose whether or not to deal damage. Creatures that lie still are simply pinned (treat as a grapple attack), while those that move or fight take 4d6 points of damage per round until they escape.

Fire Subtype (Ex): Fire immunity, double damage from cold except on a successful save.
