D&D 5E Epic Monsters: Jörmungandr

The serpent to end all serpents Jörmungandr

D&D 5E – Epic Monsters: Jörmungandr | EN World | Dungeons & Dragons | Tabletop Roleplaying Games

There are a few myths central to the world spanning Jörmungandr. One of the offspring of Loki and Angrboða (alongside its siblings Fenrir and Hel), it was first tied to a pine tree but proved feisty and spat venom at Odin. The Allgod then tossed it out into the oceans around Midgard where it grew and grew until it encircled the entire world.

After that there are three very prevalent legends: Thor lifting it thinking it was a very big cat and nearly breaking the boundaries of existence by almost getting too much of it off the ground, when Thor caught it on a fishing line that Hymir fearfully cuts in twain to prevent Ragnarök from coming too early, and finally that when the apocalypse comes that the two will slay each other.

Amphibious. Jörmungandr can breathe air and water.

Damage Threshold. Jörmungandr does not take damage from an attack, spell, or other effect that deals 10 points or less of bludgeoning, piercing, or slashing damage (calculated after resistances).

Freedom of Movement. Jörmungandr ignores difficult terrain, and magical effects can’t reduce its speed or cause it to be restrained. It can spend 5 feet of movement to escape from nonmagical restraints or being grappled.

Legendary Resistance (3/Day). If Jörmungandr fails a saving throw, it can choose to succeed instead.

Magic Resistance. Jörmungandr has advantage on saving throws made against spells and other magical effects.

Magic Weapons. Jörmungandr’s weapon attacks are magical.

Ponderous Tail. Whenever Jörmungandr makes a Colossal Tail attack, its attack does not strike until the end of its next turn. If the target of its attack has moved out of the area Jörmungandr misses the target but may hit other creatures or objects still in the area.

Regeneration. Jörmungandr regains 10 hit points at the start of its turn. If Jörmungandr takes radiant damage, this trait doesn’t function at the start of its next turn. Jörmungandr dies only if it starts its turn with 0 hit points and doesn’t regenerate.

Seamaster. At the start of any turn that Jörmungandr has pulled at least 200 feet or more of its body out of the water, its absence sends the sea tumbling. Creatures within 50 feet of the part of Jörmungandr’s body that is still submerged must make a DC 23 Strength saving throw or be knocked prone and pushed 50 feet away from it.
When Jörmungandr starts its turn with less than 200 feet of its body out of the water, creatures within 50 feet of it must make a DC 23 Strength (Athletics) check to move in the water. Any creature that has a swim speed makes this check with advantage.

Siege Monster. Jörmungandr deals double damage to objects and structures.

World Tremors (Recharge 6). Jörmungandr can use a bonus action to innately cast earthquake (DC 21) without the need for material components, somatic components, or concentration.

ACTIONS
Multiattack. Jörmungandr attacks twice: twice with its black venom, or once with its bite, and once with either colossal tail or constrict.

Bite. Melee Weapon Attack: +15 to hit, reach 30 ft., one target. Hit: 44 (6d10+11) piercing damage plus 27 (6d8) acid damage. In addition, at the end of its next turn the creature makes a DC 23 Constitution saving throw or it takes 27 (6d8) poison damage.

Colossal Tail. Melee Weapon Attack: +15 to hit, reach 120 ft., multiple targets more than 20 feet away from Jörmungandr (120-foot cone centered on one target; roll separately for each creature and object in the area). Hit: 37 (4d12+11) bludgeoning damage and the target makes a DC 23 Strength saving throw or is knocked prone.

Constrict. Melee Weapon Attack: +15 to hit, reach 20 ft., one creature. Hit: 38 (6d8+11) bludgeoning damage, and the target is grappled (escape DC 23). Until this grapple ends, the creature is restrained, and Jörmungandr can’t constrict another target.

Black Venom. Ranged Weapon Attack: +8 to hit, range 50/100 ft., multiple targets (10-foot square; roll separately for each creature and object in the area). Hit: 27 (6d8) acid damage. In addition, at the end of its next turn the creature makes a DC 23 Constitution saving throw or it takes 27 (6d8) poison damage.

Greater divine blood as progeny of a greater god and a great giant sorceress, and as primeval ouroboros serpent prophetized to rise against the gods at Ragnarok together with his brother the Fenris wolf, Jormungand has abilities which surpass even those of other Abominations, paralleling those of a god, even if he’s not a god by himself.

• He’s the equivalent of an entity with VdR18
• Does not treat a 1 on attack rolls and saving throws as automatic failure;
• Immune or resistant to divine powers. He’s immune to Annihilating Strike coming from a DR18 or lower deity, receives a fortitude save to fend off Divine Blasts or Mass Divine Blasts, and may breach Area Divine Shields or Divine Shields with a will save;
• He shares the immunities of a greater god. Apart from the infinite regeneration of his body (see below), and the immunities as an Abomination, he’s immune also to disease, stunning, Paralysis, death effects and disintegration. These immunities do not apply if the attacker is a god with DR 18 or more.

Jormungand can normally breathe water. He’s also completely immune to poison of every kind, even from a god with equal or higher DR than his VdR.

Infinite regeneration

As the Ouroborus serpent, Jormungand represents the cyclical nature of things and has strong connection to life and healing powers. The Midgard serpent regenerate instantly any kind of damage, from whatever source, inflicted to his body. Even if some kind of power would be able to sever his massive body in two, the two parts would instantly reconnect healing any damage. His only vulnerable spot is his head, which has 1820 hp.
His head heals 500 hp every round.

Breath weapon

Jormungand has two weapon breaths: a 90-long poisonous cone of corrosive gas, or a 180-line acid. Damage is 24d10. The reflex save for both is 62. Once he breathes, it can’t breathe again until 1d4 rounds later.

Constrict

Jormungand has two types of physical attacks: a bite and a constrict attack. He can constrict and/or bite in the same round, and given his almost limitless length (around 25.000 miles) he can constrict any number of opponents in a round at the same time, but he can only target a new single opponent every round. For example, if faced against three dragons, he can attack one and constrict, then in the following round attack the second and constrict him while constricting the first, and in the third round he may attack and constrict the third dragon and at the same time constricting the other two.

Jormungand can start a constrict attack if he wins a grapple check (so, first he has to succeed in a touch attack, then as a free action he makes an opposed grapple check. If he wins, in the same round he starts inflicting constrict damage, until the target wins an opposed grapple check). Note that in this case (constrict attack without first holding a victim with his bite), he does provoke an attack of opportunity.

Given the dimensions of Jormungand’s body, a creature constricted may wiggle free of the hold: a large creature can add a quarter (rounded down) of his Dexterity to his grapple check, or Escape Artist check if he has the skill. A medium creature can add half his Dexterity (rounded down). A Small creature can add two thirds of his Dexterity, rounded down. A tiny creature can add his full Dexterity. Diminutive and fine creatures can’t be constricted, as the Midgard serpent body is just too big to hold them.

Improved grab

If Jormungand hits with his bite attack, he can start a grapple as a free action without provoking an attack of opportunity. If he wins the grapple check, it establishes a hold and can constrict. He can use this attack even against colossal creatures.

Poison

The Midgard serpent’s body produces one of the most deadly poisons in the multiverse: the eitr. This substance can kill even gods and cosmic entities. As he fights and if he sustain damage on the head, his body is capable of producing more poison, and the Concentration of the eitr grows.

As Jormungand just breathe, he starts poisoning the surrounding air: every creature in 50 ft-radius from his head must save every round (fortitude DC 35) or suffer initial and secondary damage of 1d8 Constitution. The DC decrease by 5 every 20 feet (so for example at 100 feet the DC is 20)

If Jormungand bites an opponent, he inject the poison directly inside his victim. The effects are terrible: initial damage is 4d8 Constitution damage, secondary damage is death: no immunity of any kind or curative spell can save the unfortunate target. Only a greater god with the healing domain can cure the effects of the eitr, using heal or mass heal from their domains, or their Alter Reality power.

Initially, the DC save vs Jormungand’s poison is 60. Every round of combat, the DC increases by four points, and by two every single time he suffers damage on his head from a successful hit or a spell dealing damage. This deadly progression has a maximum cap of 100. If Jormungand is slain, he exales a cloud of extremely dense poison, and every being in a 100 ft radius must save at the current DC for his bite, or suffer all the poison effects.

The DC goes back to 60 if Jormungand is not damaged for seven rounds.
Eitr dissipates completely after a day outside Jormungand’s body.

Swallow

If Jormungand begins his turn with an opponent held in his mouth, he can attempt a new grapple check. If he succeed, he swallows his prey, and the opponent takes bite damage. He can swallowup to and included gargantuan opponents. A swallowed creature is supposed to be grappled, while Jormungand’s not. Given his incredible regenerative powers, there’s no way to cut a way free from inside Jormungand’s body. However, a victim may try to escape the grapple: success puts it back in Jormungand’s mouth, where it may be bitten or swallowed again.

While inside Jormungand, a victim takes 4d8 of bludgeoning damage each round, and 4d8 energy damage from acid and poison (half each). In addition, a victim should save every round against poison (DC 45) or suffer 2d8 Constitution initial and secondary damage.
