The Fungi from Yuggoth have left the AD&D Deities & Demigods and are coming to your 5E D&D to perform various horrifying experiments. Watch the skies.

These red, bat-winged creatures somewhat resemble lobsters in that they have many legs, feelers, and eyestalks, and forearms that end in great pincers. Though they appear as crustaceans, they are actually fungus creatures. (Deities & Demigods, page 46)

Mi-Go
Medium plant, chaotic evil

Armor Class 16 (natural armor)
Hit Points 27 (5d8+5)
Speed 45 ft., fly 90 ft.
Ability Scores STR 10 (+0), DEX 15 (+2), CON 12 (+1), INT 17 (+3), WIS 15 (+2), CHA 6 (-2)

Skills Medicine +7
Damage Immunities cold
Senses darkvision 60 ft., passive Perception 12
Languages Mi-Go (a language of pincer-clicks and color changes)
Challenge 2 (450 XP)

Extraterrestrial Nature. The Mi-Go does not require air. It can survive in a vacuum. It can fly through the vacuum of space.

Psionic Sensitivity. The Mi-Go has advantage on Wisdom (Perception) checks to notice the presence of creatures with an Intelligence of 2 or greater and to perceive the presence of psionic effects.

Surgical Expertise. The Mi-Go adds twice its proficiency bonus to Wisdom (Medicine) checks.

Actions

Multiattack. The Mi-Go attacks twice with its pincers.

Pincers. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8+2) slashing damage.

Brain Surgery. The Mi-Go can surgically remove an incapacitated creature’s brain and store that brain in a Brain Cylinder (see below) so that the brain continues to live. The brainless body is reduced to 0 hit points with the normal results.

Special Mi-Go Items

The Mi-Go utilize advanced technology. Here are a few examples:

Brain Cylinder. This shiny metal cylinder is about 1 foot high and 8 inches in diameter. It has three triangular sockets. The fluids and alien circuitry within the cylinder can sustain a brain and enable the brain to interface with Mi-Go technology, such as a system of speakers and microphones that permit the brain to speak and hear. Each week a brain spends within a Brain Cylinder, the creature must make a DC 13 Wisdom saving throw or lose 2 (1d4) points of Intelligence, Wisdom, and Charisma. The brain expires if any score reaches 0.

Electric Weapon. The Mi-Go’s Electric Weapon appears to be made of some alien, blackish metal cast in a warty, ovoid shape. Strange circuitry covers the weapon’s surface. When held correctly, the weapon projects a 20-foot-long, 5-foot-wide line of bluish sparks. Each creature in the line must make a DC 13 Constitution saving throw. A creature takes 5 (1d10) lightning damage on a failed save, or half as much on a successful one. If the creature’s saving throw fails by 5 or more, the target is incapacitated for 1 minute. The incapacitated target may repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Living Armor. Alien biotechnology grows these slimy, chitinous segments of fungal armor that have total weight of 20 pounds. Living Armor is medium armor that bestows AC 16 + Dexterity modifier (maximum +2). Each week it is used by a non-Mi-Go wearer, the amount of protection degrades by 1 point since only Mi-Go naturally secrete the nutrients the Living Armor needs. Also, when a non-Mi-Go removes the Living Armor, the wearer takes 2 (1d4) points of damage as the fungal plates are torn from hair and skin.

Mist Projector. This cluster of twisted metal tubes projects a 10-foot-long, 10-foot-wide cone of icy mist. Each creature in the cone must make a DC 13 Dexterity saving throw. A creature takes 7 (2d6) cold damage on a failed save, or half as much on a successful one.

At this point during the conversion of the Cthulhu Mythos in the AD&D Deities & Demigods for use with 5E D&D to point out the one major flaw with this section of the book: It doesn’t really stay true to the source material. This becomes most obvious, I think, with our next creature.

In H. P. Lovecraft’s tales, the Great Race of Yith have highly developed mental powers, and the AD&D rules hit that point by giving the Great Race some potent psionic ability. What is missing from the Great Race’s description, however, is their most impressive ability, which is their ability to project their minds across time and space to forcibly inhabit the bodies of other creatures. During the time the Yithian’s mind inhabits, say, a human, that human’s mind occupies the alien body of the Yithian. In other words, the Great Race forcibly swaps bodies with another creature, doing so across both time and space, more or less at will.

These creatures populated the world eons ago and their cities still exist buried in deserts or other out of the way places. They had a highly advanced scientific civilization, with psionics rather than magic. (Deities & Demigods, page 45)

Great Race of Yith

Armor Class 15 (natural armor)
Hit Points 84 (8d10+40)
Speed 45 ft.
Ability Scores STR 23 (+6), DEX 7 (-2), CON 20 (+5), INT 26 (+8), WIS 19 (+4), CHA 15 (+2)

Senses truesight 120 ft., passive Perception 18
Languages telepathy 240 ft.
Challenge 10 (5,900 XP)

Innate Spellcasting (Psionics). The Yithian’s innate spellcasting ability is Intelligence (spell save DC 20). It can cast the following spells, requiring no material components:

At will: dimension door
3/day: modify memory, telepathic bond
1/day: foresight (self only), mind blank (self only), time stop

Actions

Multiattack. The Yithian attacks twice with its pincers.

Pincers. Melee Weapon Attack: +10 to hit, one target. Hit: 10 (1d8+6) slashing damage.

Lightning Gun. The Yithian’s lightning gun fires a stroke of lightning forming a line 300 feet long and 5 feet wide from the Yithian in a direction it chooses. Each creature in the line must make a DC 13 Dexterity saving throw. A creature takes 14 (4d6) lightning damage on a failed save, or half as much on a successful one. The lightning ignites flammable objects in the area that aren’t being worned or carried. A lightning gun has 8 charges, after which it cannot fire until its power source is replaced.

Mind Swap. The Yithian projects its psyche through time and space, across any number of years or miles, but not from one plane to another. It picks a creature at its destination. The target must make a DC 20 Wisdom saving throw. On a failed save, the target and the Yithian swap minds. The Yithian retains its INT, WIS, and CHA, and it uses the target’s STR, DEX, and CON, but it makes Dexterity checks and saving throws at disadvantage. The Yithian retains its truesight, skills, telepathy, psionics, and Mind Swap. It gains the AC, hit points, senses, languages, and the physical abilities and characteristics of the target. The target retains its own INT, WIS, and CHA, and similarly gains the STR, DEX, CON, and other physical characteristics of the Yithian. The Yithian can communicate telepathically with the target. Once per long rest, the target can make a new Wisdom saving throw. If the saving throw succeeds, the Mind Swap is reversed.

Reactions

Quick Mind. If a target resists or overcomes the Yithian’s Mind Swap, the Yithian may choose a new creature to target with Mind Swap as a reaction.

My next stop in the AD&D Deities & Demigods is the sanity-threatening Cthulhu Mythos. For the first post, I present the Byakhee, those monstrous servants of He Who Must Not Be Named, statted for 5E D&D.

These giant furry bat-like creatures have humanoid legs that enable them to stand like men. They can be summoned by clerics of Hastur through use of a gate spell (1-4 Byakhee will appear). (Deities & Demigods, page 44)

The Byakhee has two claw attacks, each of which can grapple one target.

Reactions

Abduct. When a Byakhee has restrained a target with its claws, at the end of a target’s turn if that target remains restrained, the Byakhee may attempt to plane shift to Carcosa. The restrained target must make a DC 13 Charisma saving throw. If the target fails, the target and the Byakhee are transported to Carcosa.
