Infernal Corruption.

The slug’s slime seeps into stone and metal, corroding what it touches. Each 5-foot square it moves across becomes difficult terrain until cleaned with holy water or purify food and drink. Unattended structures take 10 (3d6) acid damage per minute of contact.

Stench of Maladomini.

Any creature that starts its turn within 30 feet of the slug must succeed on a DC 18 Constitution saving throw or be poisoned until the start of its next turn. A creature that fails by 5 or more is also nauseated, suffering disadvantage on attack rolls and ability checks. On a success, the creature is immune to this stench for 24 hours.

Regeneration.

The slug regains 10 hit points at the start of its turn. It doesn’t regenerate if it takes damage from a good-aligned weapon or a spell with the good descriptor.

Magic Resistance.

The slug has advantage on saving throws against spells and other magical effects.

---

Actions

Multiattack.

The Maladomini Slug makes one Bite attack and one Bile Jet attack if available.

Bite. Melee Weapon Attack: +11 to hit, reach 10 ft., one target.

Hit: 19 (3d8 + 7) piercing damage plus 10 (3d6) acid damage, and the target must succeed on a DC 18 Constitution saving throw or contract Filth Fever.

Filth Fever. After 1 hour, an infected creature’s hit point maximum decreases by 5 (1d10) and its Dexterity and Constitution scores are reduced by 1 each day. The disease can be cured by lesser restoration or similar magic.

---

Bile Jet (Recharge 5–6).

The Maladomini Slug spews a torrent of corrosive bile in a 40-foot cone. Each creature in that area must make a DC 18 Dexterity saving throw, taking 45 (10d8) acid damage on a failed save, or half as much on a successful one.
Creatures that fail must also succeed on a DC 18 Constitution saving throw or be poisoned until the end of their next turn.

---

Bile Splash (Reactive).

When the Maladomini Slug takes damage from a melee weapon attack that deals piercing or slashing damage, acid sprays from its wounds. The attacker must make a DC 18 Dexterity saving throw, taking 18 (4d8) acid damage on a failed save, or half as much on a successful one.

---

Reactions

Vile Retaliation.

When hit by a melee attack, the Maladomini Slug lashes out instinctively, making one Bite attack against the attacker.

---

Legendary Actions

The Maladomini Slug can take 2 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn. The slug regains spent actions at the start of its turn.

• Detect. The slug makes a Wisdom (Perception) check.
• Crushing Advance. The slug moves up to half its speed without provoking opportunity attacks.
• Acidic Ooze (Costs 2 Actions). The slug secretes burning slime in a 10-foot radius. The area becomes difficult terrain, and creatures entering or starting their turn there take 9 (2d8) acid damage.

---

Tactics

A Maladomini Slug advances like a siege engine wrapped in living filth. It opens combat by spewing its Bile Jet to saturate the battlefield, then crawls forward, spreading its Infernal Corruption and forcing foes into confined, acidic ground. It punishes melee attackers with Bile Splash and relies on its Regeneration and Magic Resistance to outlast its enemies. Patient and purposeful, it fights until every structure—and every mortal—has collapsed into ruin in the name of Beelzebub’s perfection.

ECOLOGY

Environment any (Hell—Maladomini)
Organization solitary or cluster (2–6)
Treasure none

Maladomini slugs are massive, translucent fiends whose glistening flesh reveals the churn of bile and filth within. Their endless purpose is to erode the imperfect creations of mortals and devils alike, reducing stone to sludge so that Beelzebub may rebuild his dominion according to his twisted vision of infernal perfection. They slither through crumbling infernal cities and ruined mortal temples, devouring stone, metal, and sanctified relics with equal appetite.

---

TACTICS

Before Combat A maladomini slug emerges from beneath ruined foundations or walls, filling the air with its stench before unleashing its breath weapon to scatter clustered foes.
During Combat The slug advances slowly but inexorably, using acid fog to control the battlefield and drive enemies into confined spaces. It relies on its regeneration and damage reduction to endure assaults while bathing enemies in corrosive bile.
Morale A maladomini slug fights until destroyed, its mind consumed entirely by Beelzebub’s directive to cleanse imperfection through decay.

LORE

Knowledge (planes)
DC 20 – This creature is a devil spawned from Maladomini, the seventh layer of Hell, tasked with spreading decay and corrosion.
DC 25 – Its slime eats through even enchanted stone, and its bile burns with infernal acid.
DC 30 – Created by Beelzebub himself, these slugs are used to erase flawed architecture so that the Lord of Flies may rebuild it in his own grotesque image.

DESCRIPTION

A Maladomini Slug is a lumbering mass of translucent gray flesh, its bloated body sloshing with bile and pestilence. A dozen lidless eyes cluster around a gaping, toothed maw that drips acid thick enough to etch steel. Despite its sluggish form, every movement radiates malevolent purpose—the will of Beelzebub made manifest through slow, relentless desecration. Its passage transforms shining marble to foul sludge, leaving behind only ruin and the stink of damnation.

Cocytus Slug

A slimy, gray slug, the size of an ogre, makes it way towards you. Its skin is see-through and reveals that it is filled with bile, filth, and other unknown liquids and substances. A multitude of eyes dot its sluggish head, while a gaping maw appears just beneath them.

Cocytus slugs are the rarest product of Beezlebub they serve him by spreading filth and destruction. Beelzebub‘s puts them in charge of specifically destroying buildings so that he may reshape them and make them ‘perfect’, which is sort of like what he’s doing in his own layer, Cocytus. These infernal slugs continually spread mayhem in the name of their master, Beelzebub.

Cocytus slugs stand 9 ft tall at the ‘shoulder’, and are 12 ft. long. They weigh close to a ton and speak Common and Infernal languages.
