Mu Spore

Windsense 240 feet — The mu spore senses vibrations in the air through its aerial spores.

Regeneration 50 (Deactivated by Sonic) — 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.

Enormous — A mu spore is a massive creature and takes up a space of 10 squares by 10 squares (50 feet by 50 feet).

Grasping Tendrils —

Spores (aura) — 60 feet. A living creature that enters the area or ends its turn within it is corrupted by spores. It must succeed at a DC 42 Fortitude save or be Clumsy 1, Enfeebled 1, and Slowed 1 for 1 round. Fungi and plants are immune.

Cough Spores — The mu spore releases a cloud of burrowing spores in a 400-foot cone. The spores deal 22d6 piercing damage to all creatures, objects, and wooden structures in the area, but not to plants or fungi (DC 46 Reflex save).

The mu spore can't use this ability again for 1d4 rounds.

Enormous Inhalation — The mu spore pulls all creatures and objects in a 400-foot cone 400 feet towards it's mouth. A successful DC 43 Fortitude save halves the distance, or avoids the pull on a critical success. The mu spore automatically attempts to Swallow Whole each creature adjacent to it at the end of the inhalation.

Fast Swallow —

Greater Constrict — 15 bludgeoning, DC 45 Fortitude

The monster deals the listed amount of damage to any number of creatures Grabbed or Restrained by it. Each of those creatures can attempt a basic Fortitude save with the listed DC. A creature that fails this save falls Unconscious, and a creature that succeeds is then temporarily immune to falling unconscious from Greater Constrict for 1 minute.

Overpowering Jaws — The mu spore still deals 18 piercing damage if its jaws Strike is a failure

Swallow Whole (attack) — Gargantuan, 20d6+9 acid damage, Rupture 37.

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.
