Mobogo

Constant Spells — A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

Regeneration 30 (Deactivated by Acid, Cold, or Fire) — This monster regains the listed number of Hit Points each round at the beginning of its turn. Its Dying condition never increases beyond Dying 3 as long as its regeneration is active. However, if it takes damage of a type listed in the regeneration entry, its regeneration deactivates until the end of its next turn. Deactivate the regeneration before applying any damage of a listed type, since that damage might kill the monster by bringing it to Dying 4.

Song of the Swamp (auditory, emotion, mental, primal) — Frequency once per 10 minutes

Effect The mobogo unleashes a booming croak. All boggards and mobogos within 50-foot emanation{50 feet} gain a +2 status bonus to damage rolls and saves against fear for 1 round. Other creatures in the area of effect must attempt a DC 27 Will save.

Success The creature is unaffected and is temporarily immune for 24 hours.

Failure The creature is Slowed 1 for 1d4 rounds.

Critical Failure The creature is Slowed 2 for 1d4 rounds.

Swallow Whole (attack) — Large, 2d12+6 bludgeoning, Rupture 19

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.

Swamp Stride — A mobogo ignores difficult terrain caused by swamp terrain features.

Tongue Grab — A creature hit by the mobogo's tongue becomes Grabbed by the mobogo. The creature isn't Immobilized, but it can't move beyond the reach of the mobogo's tongue.

A creature can sever the tongue with a Strike against AC 27 that deals at least 10 slashing damage. This deals no damage to the mobogo but prevents it from using its tongue Strike until it regrows its tongue, which takes 1 round.

The mobogo can move without ending the Grab as long as the creature remains within the tongue's reach.

Tongue Reposition — When a mobogo successfully Repositions a creature Grabbed by their tongue, they increase the distance they can move that creature by 10 feet (a total of 15 feet on a success or 20 feet on a critical success); the creature must remain within the tongue's reach. Alternatively, the mobogo can transfer the grabbed creature to being grabbed by the mobogo's jaws.

Improved Grab —
