The Midgard Serpent can focus its gaze on one creature which must succeed a DC 23  Wisdom  saving throw or become  charmed  by the Midgard Serpent. A  charmed  creature can attempt a saving throw at the end of each of its turns to end the condition. \n'b'  God-Eater .

This creature is loyal to the Midgard Serpent and will do anything to defend it. \n'b' The Midgard Serpent can cause a 10-foot-radius square of water within 60 feet to superheat.

All creatures within this area must succeed a DC 23  Dexterity  saving throw or be  restrained  for 1 round. \n'b'\n'b' Regional Effects \n'b' The region containing the Midgard Serpent\xe2\x80\x99s lair is shaped by its titanic power, which creates one or more of the following effects: \n'b'\n'b' Underwater lightning storms become frequent, with electricity occasionally arcing through the sea floor and hotspots of boiling water becoming commonplace \n'b' Religious symbols become hot to the touch, almost becoming unbearable to wield within 1 mile of the Midgard Serpent\xe2\x80\x99s lair. \n'b' The lighting within 1 mile of the Midgard Serpent\xe2\x80\x99s lair becomes dim lighting that is impossible to brighten. The area within 150 feet of the Midgard Serpent\xe2\x80\x99s lair is  darkness  that is impossible to brighten. \n'b'\n'b' About \n'b' The Midgard Serpent is the greatest of linnorms, the unbounded spawn of a treacherous godling and his monstrous bride. Cast into the sea by the when it and its monstrous siblings were discovered, this beast is fated to one day devour the mightiest of the gods. The Midgard Serpent\xe2\x80\x99s appetite is endless, as it gorges itself for weeks at a time before descending into the deepest depths of the ocean to drift in the inky depths for years or decades at a time before rising once more to feast. Also called Jormungandr, the Midgard Serpent is over 500 feet long and weighs over 20,000 tons. \n'b'  Legendary Destroyer . The Midgard Serpent is a solitary beast, tolerating no rivals in the deep waters where it swims. It preys upon ordinary aquatic animals like whales and squid, but also happily devours dragon turtles, krakens, and lesser linnorms, and can depopulate entire cities of aquatic races like  sahuagin  and  merfolk . When it roams close to the surface, storms follow in its wake, and ships are shattered with ease beneath its coils as their crews are devoured. On rare occasions it ventures near to shore, usually when pursuing a ship fleeing before it, and may devastate coastal communities with its onslaught as the storm-tossed sea rises up around it, but it soon retreats to the deep oceans it favors. \n'b'  God-Eater . The Midgard Serpent is a unique creature, though kin to other great monsters like Fenris Wolf sired by the same forbidden liaisons that gave birth to it. Cast into the sea by the gods long ago, the Midgard Serpent still holds great enmity toward them and their servants, and seeks out divine servants to devour with especial relish. If he chances upon shrines to the gods, he always takes the time to demolish, despoil, and pollute them, vomiting forth his vile and corrupted poisons into the ruins left behind. Jormungandr is not particular in his hatred of the gods, and is equally happy to destroy spaces both sacred and profane. He is a devourer of both magic as well as flesh, consuming the latent magical energies of the world and drawing in the life-giving essence of the universe with every breath. His presence disrupts natural weather and brings with it disastrous storms and a dimming of the light of the world. \n'b' He is a creature of pure hate, looking always towards that faroff day when the world draws down to its bitter, frozen ending and he and the other great beasts of the world rise up and devour the gods who once cast them down.'
