Creeper (Forge)

Creepers are non-intelligent gelatinous organisms that move about using pseudopodia. They do not possess sensory organs but detect prey via vibration and scent at a range of 80 feet. They are semi-transparent and difficult to detect, allowing them to surprise prey 80% of the time.

These creatures can move along any surface (wall, floor, ceiling, etc.) and pass through small cracks and under doors.

When creepers reproduce, they do so by devouring large amounts of carrion and then splitting into two halves. Each half becomes a distinct creature, and they immediately seek separate hunting grounds.

Creepers live in subterranean areas. They survive by devouring the flesh and fluids of recently killed creatures. They feed on rats, bats, and other warm-blooded animals but attack humanoids too. Creepers are aggressive hunters and attack without provocation or hesitation.

Ordinary creepers appear as pools of gelatinous liquid covering a two-square-foot area.

When entering combat, a creeper attacks by spewing digestive fluids at its victim. This attack requires a d20 attack roll, but the creeper must only strike their victim’s DV2. Each successful hit inflicts 1d3 actual damage from acid. The fluids are acidic enough to damage flesh but not harm metal, wood, or stone.

Creepers travel alone, but adventurers claim to have encountered groups between two and five.

Greater creepers have a gelatinous mass covering a five-square-foot area and appear several inches thick.

In combat, a great creeper spews its digestive fluids upon melee victims. This attack requires a d20 attack roll, but the greater creeper must only strike its victim’s DV2. If successful, the greater creeper’s acid inflicts 2d4 actual damage. Although the creature’s digestive fluid burns flesh, it does not harm metal, wood, or stone.

These monsters are solitary creatures, and encounters with more than one have never been documented.
