Absorb Flesh (Ex)
A carnivorous blob cannot eat plant matter or inorganic matter, but it devours living flesh with a voracious speed by dealing Constitution drain on creatures it slams or maintains a grab. Whenever the blob deals Constitution drain in this manner, it heals 10 Hit Points for each point of Constitution it drains.
Excess Hit Points above its normal maximum are gained as temporary Hit Points. As soon as a carnivorous blob has at least 50 temporary Hit Points, it loses those temporary Hit Points and splits as an immediate action.
Reactive Strike (Ex)
Whenever a carnivorous blob takes damage, it reflexes lashes out with a slam attack, targeting the creature dealing damage to it if the creature is adjacent to it. Attacks that deal sonic or slashing damage do not trigger a reactive strike (instead, causing the blob to split).
Whenever a carnivorous blog takes cold damage, it cannot use its reactive strike ability until after it takes its next action in combat.
A carnivorous blob splits into two identical copies of itself if subject to sonic or slashing damage. Each copy has half the original’s current Hit Points (rounded down). A carnivorous blob reduced below the listed Hit Points cannot be further split and can be killed normally.
While sages debate whether the first carnivorous blobs were created by a mad wizard, formed in foul fleshwarping vats in some sinister city, or traveled to this world trapped in the core of a meteor, there is one thing they all agree on—none wish to get close enough to study the monstrosity. Carnivorous blobs move like a typical ooze, rolling out blobs of its fleshy material in haphazard directions, and pulling its bulk across the ground, up walls, and even through the water. If a carnivorous blob goes for more than 24 hours without a source of food, it drops into a sort of hibernation, resembling nothing so much as a pool of gelatinous blood.
The creature springs to life quickly and hungrily as soon as any living prey comes within range of its senses.
