Swallow Whole (Ex)

If the creature hits with the indicated attack (usually a bite attack), it deals the normal damage. If the creature’s attack roll hits the target’s KAC + 4, the creature also automatically grapples the foe as part of the attack action. (If it hits the target’s KAC + 13, it instead pins the target). The creature doesn’t need to have a free limb to perform this grapple. Unless otherwise specified, a creature can swallow whole only targets that are at least one size category smaller than itself, and it has room for a single target of that size in its stomach (doubling the maximum number of creatures it can have swallowed for each additional size category by which these creatures are smaller).
On the creature’s next turn after grappling or pinning the target, if the target hasn’t escaped the grapple or pin, the target automatically takes the attack’s damage at the beginning of the creature’s turn. The creature can then make a new attack roll with the same attack. If the roll equals or exceeds the target’s KAC, the grapple or pin is maintained. If the roll equals or exceeds the target’s KAC + 4, the target is swallowed whole (no damage is dealt).
Once swallowed, the target takes the listed swallow whole damage automatically at the beginning of its turn every round. The target is considered grappled as long as it’s swallowed. The target can attempt to cut its way out (the interior of a creature with swallow whole has the same EAC as its exterior and a KAC equal to that of its exterior – 4) by dealing an amount of damage equal to one-quarter the swallowing creature’s total Hit Points, though any attack that doesn’t deal slashing damage deals only half its normal damage. If a target cuts its way out of the creature, the creature can’t use swallow whole again until that damage is healed.
Alternatively, a swallowed target can attempt to climb out. The swallowed creature must succeed at both a grapple check against the creature’s internal KAC + 8 and an Athletics check to climb (DC = 10 + 1-1/2 × the creature’s CR). Each of these actions takes a full round. If both checks are successful, the target climbs back up to the creature’s mouth and can escape, ending up in an open square adjacent to the creature.

Format: Melee bite +19 (5d4+16 P plus swallow whole); Offensive Abilities swallow whole (5d4+16 A, EAC 30, KAC 27, 71 HP).
Guidelines: Use the same damage amount as for the creature’s standard melee attack.
