Rift Chameleon

The rift chameleon's innards exist partially on the Ethereal Plane, allowing it to swallow any number of creatures, even ones larger than itself. Creatures that Escape or cut themselves free from the chameleon's stomach reappear in the Universe adjacent to the rift chameleon's position. Creatures cannot escape from the rift chameleon's gullet using teleportation effects unless those effects can also cross planar boundaries.

Frequency once per round Effect The rift chameleon Strides twice. During this movement, it flits quickly between the Universe and the Ethereal Plane, gaining resistance 5 to physical damage.

This monster can see in all directions simultaneously and therefore can't be flanked.

A rift chameleon can Hide, even if it doesn't have cover, but it cannot be Concealed from creatures on the Ethereal Plane.

Large, (1d12+2) bludgeoning, Rupture 10 The monster attempts to swallow a creature of the listed size or smaller that it has grabbed or restrained in its jaws or mouth. If a swallowed creature is of the maximum size listed, the monster can't use Swallow Whole again. If the creature is smaller than the maximum, the monster can usually swallow more creatures; the GM determines the maximum. The monster attempts an athletics check opposed by the grabbed creature's Reflex DC. If it succeeds, it swallows the creature. The monster's mouth or jaws no longer grab a creature it has swallowed, so the monster is free to use them to Strike or Grab once again. The monster can't attack creatures it has swallowed. A swallowed creature is Grabbed, is Slowed 1, and has to hold its breath or start suffocating. The swallowed creature takes the listed amount of damage when first swallowed and at the end of each of its turns while it's swallowed. If the victim Escapes this ability's grabbed condition, it exits through the monster's mouth. This frees any other creature grabbed in the monster's mouth or jaws. A swallowed creature can attack the monster that has swallowed it, but only with unarmed attacks or with weapons of light Bulk or less. The swallowing creature is Off-Guard against the attack. If the monster takes piercing or slashing damage equaling or exceeding the listed Rupture value from a single attack or spell, the swallowed creature cuts itself free. A creature that gets free by either Escaping or cutting itself free can immediately breathe and exits the swallowing monster's space. Effect: Engulf and Swallow Whole If the monster dies, a swallowed creature can be freed by creatures adjacent to the corpse if they spend a combined total of 3 actions cutting the monster open with a weapon or unarmed attack that deals piercing or slashing damage.

Any creature hit by the rift chameleon's tongue is pulled adjacent to the chameleon. The creature is Off-Guard to the next Strike the rift chameleon makes against it this round.
