Ink-Slick Amalgam - AI-generated fantasy Monster

Ink-Slick Amalgam

Folklore in the dreary town of Oakhaven speaks of the 'Leaking Shadows.' Local legends claim that the more the town's industry polluted the groundwater, the more the shadows themselves began to detach from the walls and walk.

ChallengeMedium
Amorphous. The amalgam can move through a space as narrow as 1 inch wide without squeezing.
Ichor Invisibility. While fully submerged in liquid, the amalgam is invisible.
Mimic Silhouette. As a bonus action, the amalgam can shape itself into a humanoid silhouette. While it remains motionless in this form, it is indistinguishable from a regular shadow cast on a wall or a person standing in deep gloom.

Actions

Multiattack. The amalgam makes two Enveloping Slap attacks.
Enveloping Slap. Melee Weapon Attack: to hit, reach 5 ft., one target. Hit: 10 () bludgeoning damage plus 7 () acid damage. The target's Strength score is reduced by . The target dies if this reduces its Strength to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.
Ichorous Pulse (Recharge 5-6). The amalgam releases a splash of sticky ichor in a 15-foot cone. Each creature in that area must make a Strength saving throw. On a failure, a creature takes 14 () acid damage and is Restrained. On a success, it takes half as much damage and is not restrained. A creature can repeat the saving throw at the end of each of its turns to end the effect.

Reactions

Oily Escape. When the amalgam takes damage from a melee attack, it can use its reaction to move up to half its speed without provoking opportunity attacks.

Notes for the game master

Remember that the Strength drain is cumulative over multiple turns.
Invisibility in water applies even if the water is clear.

Tactics

  1. Opening

    Lures a victim into a damp area or narrow alleyway while disguised as a slumped person. It initiates combat with Ichorous Pulse to restrain the group.

  2. Mid-fight

    Focuses on the physically strongest character to sap their Strength, making it harder for them to escape its reach.

  3. End of the fight

    If surrounded, it uses its swim speed or Amorphous trait to slide into the floorboards or down a well.

  4. Retreat

    The amalgam is relentless until it reaches 25% health, at which point it seeks the nearest body of water to hide.

How it fights

Targets Clerics and Paladins first to remove cleansing threats.
Stays near puddles to maximize its Oily Escape.

Who it attacks first

Strongest physical attackers (Fighters/Barbarians)
Visible spellcasters with light-based magic

Works well with

Shadows
Will-o'-Wisps
Grey Oozes

How to beat it

Sunbeam or Light-based spells
Force damage
Telekinetic shoves into dry areas

Ways to avoid a fight

Players can attempt to 'wash' the amalgam away with large quantities of pressurized clean water or holy water.
Offer it a large supply of raw meat or oils to distract it.

Ecology

In its natural state, it is a puddle of viscous, tar-like black ichor that reflects light with a rainbow-slick sheen. When hunting, it rises into a shivering, featureless silhouette of a humanoid, its surface bubbling and dripping. In water, it becomes a faint, oily distortion barely visible to the naked eye.

Behavior

It prefers to lurk in damp basements, wells, or rain-slicked alleys. It waits for lone travelers, assuming a slumped humanoid posture to look like a person in distress before lunging. It is patient and driven by a primal hunger for the 'vitality' stored in muscle and bone.

How it lives

The Amalgam is often the byproduct of alchemical waste mixed with necromantic energy. It does not reproduce naturally but splits when it has consumed enough 'strength' from its victims.

Lair

An abandoned tanner's basement or a stagnant town cistern where the walls bleed a constant, thin film of black oil.

Habitat
Urban ruins, damp cellars, rural wells, sewers

Signs that it is near

Sticky black stains on doorframes
Faint smell of kerosene and rot
Absence of local vermin in specific damp areas

Lore

Folklore in the dreary town of Oakhaven speaks of the 'Leaking Shadows.' Local legends claim that the more the town's industry polluted the groundwater, the more the shadows themselves began to detach from the walls and walk.

What drives it

After the fight
