Actions/Abilities/Traits: (OSR)
Special
|Swallow Whole
The creature makes one bite Attack as a full-round action against a victim it has struck successfully the round prior. If the Attack hits, the target is swallowed. The swallowed target is Blinded and Restrained, it has total cover against attacks and other Effects outside the creature, and it takes cold damage at the start of each of the creature's turns. The creature can have only one target swallowed at a time. If the creature dies, a swallowed creature is no longer Restrained by it and can escape from the corpse using 5 feet of Movement, exiting prone. Swallowed creatures take damage each round equal to 1/4 this creature's weakest normal melee attack until they escape; escaping requires cutting your way out (AC as creature; stomach has HP equal to 1/4 the creatures' total HP max).
