There exists dimensions beyond our own. And what dwells in those realms? Entities far beyond our comprehension, of course! Only a fool would research too deeply into such theories, as they’re liable to go mad from either dark truths or being constantly called a liar and a fool.
Author’s Note: It’s been a while since I’ve done something truly inspired by H.P. Lovecraft’s brand of horror. While my personal campaign has inject Lovecraftiana into a Barrier Peaks homage (making it more Firestorm Peak), my blog has been lacking in that. So, let’s revisit Cosmic Horror by revisiting some of my older monsters! Enjoy.
Eldritch Ooze
This tar-like goo slithers slowly along a surface, sneaking into various crevices while it awaits a host.
Small Aberration; always lawful, usually lawful evil
Armor Class 14 (natural armor)
Hit Points. 82 (11d6 + 33)
Speed 30 ft., Climb 30ft. (any surface)
STR 6 (-2), DEX 19 (+4), CON 18 (+4), INT 16 (+3), WIS 13 (+1), CHR 8 (-1)
Saving Throws Str +4 Wis +4 Chr +2
Damage Resistances. bludgeoning, piercing, and slashing from weapons (including magic weapons), necrotic, radiant
Damage Immunity. cold, psychic, poison
Weakness. acid, fire, lightning
Condition Immunities charmed, fatigued, poisoned
Senses blindsight 120 ft., passive perception 14
Languages all (cannot speak unless inside a vessel), telepathy (with bonded subjects and other Eldritch Oozes) 120 feet.
Challenge 4 (1,100 XP)
Amorphous Shape. It is a challenge to properly strike this creature while it is not leeching off a victim. When the Ooze isn’t actively engaged in combat against a specific creature (or in the process of trying to take over a victim), all attackers have disadvantage against it. Furthermore, the ooze has advantage on dexterity saving throws against spells and magical effects targeting it. While the Ooze is engaged in trying to seize a victim, it loses this benefit.
Generate Spawn. After controlling a host for at least 1 month, it can generate 1 spawn. No more than 2 Eldritch Oozes can take up a host’s body at once.
Leaping Strike. When the ooze chooses a target within 15 feet of it, it can leap over to the creature as part of its attack action.
Spider Climb. The ooze is capable of scaling almost any surface.
ACTIONS.
Multiattack. The Eldritch Ooze may attack with Crawling Terror twice per round. However, it may choose to use Seize Control instead, if it succeeds a Crawling Terror attack and the victim fails a saving throw.
Crawling Terror. Melee Weapon Attack. +7 to hit, reach 5 ft., one target. Hit: 6 (1d4+4) psychic damage. The subject must make a DC 15 Charisma saving throw or be restrained. Furthermore, the Ooze merges with the subject. Until ooze is willed out, the only way to damage it is attacking the target it has bonded with.
Seize Control. Melee Weapon Attack: +6 to hit, targets creature it has crawled into. Hit: 8 (2d4+3) psychic damage. The subject must make a DC 10 Charisma saving throw or be Charmed for 1 round. Any target brought down to 0 by this creature is dominated under its control, becoming an Ooze Slave. If the Eldritch Ooze is killed while inside of the Slave, they are freed from control and the Ooze dissolves into nothingness.
Besides nasty damage, this can also lead to being possessed (dominated) by the Ooze. If the creature drops to 0 HP while dominated, they must do a Charisma saving throw or become an Ooze Slave.
TEMPLATE: Eldritch Ooze Slave
Any creature that becomes taken over by an Eldritch Ooze has become an Ooze Slave. These creatures look mostly indistinguishable from their old selves, save for a black inky film across their eyelids. Their new master aids them in diverting suspicion from them. In return, their master directs them into densely populated areas to ensure the Eldritch Ooze can spread its terror
Any living creature, preferably humanoid, is capable of becoming an Ooze Slave. When a creature becomes an Ooze Slave, it retains all its statistics except as noted below:
- Senses. The Ooze Slave gains blindsight with a radius of 60 feet.
- Languages. The Ooze Slave gains telepathy out 60 feet. However, it can only communicate with other Eldritch Oozes and Ooze Slaves, with the Eldritch Ooze issuing out commands.
- Resistances. The Ooze Slave gains a resistance to poison and psychic damage.
- Mundane Bluff. The Ooze Slave gains advantage on all deception checks and checks with a disguise kit to blend into its surroundings.
- Sturdy Grip. The sticky black ichor mixed with the numbness of the mind slave results in a terrifying grappler. Ooze Slaves have advantage on checks to grapple or restrain a target.
- Retainer. As long as the victim is controlled, 1 – 2 oozes occupy them. Should the victim die, the Ooze forcefully ejects itself, much like its Leaping Strike ability. Should all oozes flee the subject, they lose this template and are no longer considered an Ooze Slave.
Puppeteer Parasite
At your side is a grotesque small creature with a head similar to a green colored leech. Its body looks like a heavily mutated simian creature sporting massive digging claws. The things skin is rough and leather, all while looking almost putrid. The creature’s beady little eyes survey you, as if the creature is studying you.
Small aberration, neutral evil
Armor Class 15 (natural armor)
Hit Points 42 (8d6+16)
Speed 25 ft.
STR 15 (+2) DEX 18 (+4) CON 14 (+2) INT 13 (+1) WIS 12 (+1) CHA 16 (+3)
Saving Throws. STR +4, INT +3
Skills. Acrobatics +6, Deception +5, Perception +5
Damage Resistances. bludgeoning/piercing/slashing damage from non-magical weapons
Damage Immunities. psychic
Condition Immunities. charmed, exhausted, frightened
Senses Darkvision 120 ft., Passive perception 15
Languages. Deep Speech
Challenge 5 (1,800 XP)
Bodily Mimicry. When possessing a body that it has burrowed into, it will pretend to act like its host; whether a living person or a still corpse. It has advantage on Charisma (Deception) checks related to coming across as the creature it is inhabiting.
Horrible Leap. The parasite can spend 1/2 of its movement (round up to 15ft.) leaping at an enemy, if it ends within melee range of a target and attacks. If the victim is hit, it must make a Dexterity saving throw (DC 14). Failure results in being restrained by the parasite. The parasite may do this as long as it is currently not within melee range of a target.
Possession. If a parasite reduces a creature’s HP to 0, the target must make a Constitution saving throw (DC 14) or immediately become dominated by the parasite as a reaction. The creature merges with its victim by doing this. Attacking the parasite will damage the victim instead, until the victim is killed. The parasite may choose to animate corpses in addition to controlling unconscious targets.
ACTIONS
Multiattack. The puppeteer parasite can make two Scythe Hand attacks. If the target has been restrained or grabbed, the parasite may choose to use Burrow in place of one of its attacks.
Scythe Hand. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 15 (2d10 + 4) slashing damage.
Burrow. Melee Weapon Attack: +6 to hit, reach 5 ft., a creature it has jumped on or grabbed. Hit: 21 (3d10+4) piercing damage
REACTIONS
Agile Feet. The Parasite is quite observant of a foe, especially when not actively trying to possess them. When attacked, it can use its reaction to gain a +5 bonus to its AC versus that attack. However once the attack is resolved, this bonus goes away.
Parasite’s Puppet Template
Creatures possessed by this creature are at the mercy of its whims. They no longer have any control over their actions, if they weren’t already killed prior to possession. Creatures possessed by a parasite receive the following qualities:
- Ability Scores: Gain the Intelligence, Wisdom and Charisma score of the parasite if scores are not already higher
- Alignment: Becomes Neutral Evil
- Corpse Puppet: See Monster Ability
- Deathly Burst: When this creature is brought to 0 HP, the parasite will burst forth from the body. All creatures within 30 ft. must make a Wisdom saving throw. Failure results in taking 19 (3d12) psychic damage. Success results in half damage. Following this, a parasite is spawned in their place.
The Patchwork Devourer
This vaguely humanoid figure looks to be composed of several animated images depicting the deaths of countless creatures. The illuminated creature shuffles with an uncanny gate, as it emits screams and moans from the countless victims it has murdered in a maddening loop. While the creature gives off no warmth, it seems oddly allured to it. Worse yet, flames do nothing to it but entice it more.

Dream Thief
What can only be described as a cross between a minuscule pixie-like creature, a root vegetable and a mosquito with rows of little red eyes going down its head.
