Tremorsense 60 feet

Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.

Bloodsense 120 feet

The Bloodstorm can precisely sense bleeding creatures within 120 feet.

Biting Constrict

Requirements The Bloodstorm is in Demon Shape and has a creature Grabbed

---

Effect The writing mass of the Bloodstorm's pincer bites the grabbed creature, dealing (3d8+8) piercing damage (basic Fortitude save). On a failure, the creature also takes 1d8 persistent,bleed damage.

---

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.

Biting Swarm

Each creature in the Bloodstorm's space takes 3d6[piercing],3d6 slashing damage (DC 31 fortitude save). Creatures that fail their saving throw also take 1d8 persistent,bleed damage.

Demon Shape

The swarm condenses into the solid shape of a shemhazian demon. While in this form, it's a gargantuan creature, cannot share the space of another creature, and can use its pincer attack. It loses its resistance to physical damage as well as its weaknesses to area and splash damage. Any creatures sharing a space with the Bloodstorm when it transforms are pushed into the nearest empty space. The Bloodstorm can use this action again to revert to its swarm shape.

Feeding Frenzy

Requirements There are bleeding creatures in the Bloodstorm's space

---

Effect The bleeding creatures take 3d8[piercing],3d8 slashing damage (DC 34 fortitude save). The Bloodstorm gains temporary Hit Points equal to half of the damage dealt this way.

Improved Grab

Trigger The monster's last action was a successful Strike that lists Improved Grab in its damage entry, or the monster has a creature Grabbed or Restrained

---

Effect If used after a Strike, the monster attempts to [/act grapple] the creature using the body part it attacked with as a free action. This attempt neither applies nor counts toward the creature's multiple attack penalty.

The monster can instead use Improved Grab as an action and choose one creature it's grabbing or restraining with an appendage that has Improved Grab to automatically extend that condition to the end of the monster's next turn.

A hundred thousand leeches, mosquitos, and parasites form a roiling mass of hunger and malice. It moves like a storm through the tunnels and caverns of the Emperor's Peak, constantly in search of its next meal. Though it has many bodies, it has just one, startlingly clever mind. The flames and smoke of the cities keeps it at bay, but in the darkness, it is at home. The dwarves of Highhelm have learned how to live with the threat, but those traveling deeper into the mountain must always remain vigilant.

In the swamps of the Tanglebriar, food is difficult to come by. So when a grievously wounded demon, a shemhazian known as Gratheyr, fled into its waters to escape from his enemies, every starving creature swarmed at the smell of blood. As the creatures devoured his flesh, they were corrupted by his Abyssal blood, and their hunger only grew. They feasted until nothing but his heart remained, still beating at the center of the swarm, binding it to a single will. With its meal finished, the bloated swarm left the swamp in search of its next prey. It moved aimlessly, hunting animals and travelers alike, until a great rumble beneath the earth attracted its attention. The Bloodstorm followed the vibrations deep underground, toward the scent of sweat and the sounds of voices.
