Magic Resistance. The yochlol has advantage on saving throws against spells and other magical effects.

Spellcasting. The yochlol uses Divinity (cha) to cast spells (spell save Difficulty 14, +5 to hit with spell attacks). It has 10 mana, a mana limit of 2, regains all expended mana when it finishes a long rest, and regains half its total mana when it finishes a short rest. It knows the following spells:

At will: detect thoughts, web

Cantrips (at will, 13th-level spellcaster): poison spray

1 mana: blinding poison, confusion poison, detect poison, envenomed weapon, lingering poison, poison burst, poisoning strike, protection from poison, putrefy food and drink, sicken, slowing poison, toxic fumes

2 mana: cloudkill, halo of spores, insanity mist, mind control, neutralize poison, noxious plume, paralytic poison, poison bane, stinking cloud

Spider Climb. The yochlol can climb difficult surfaces, including upside down on ceilings, without needing to make a skill check.

Web Walker. The yochlol ignores movement restrictions caused by webbing.

Actions (2)

Slam (Demon Form only). Melee Weapon Attack: +5 to hit, reach 2 m. Hit: 5 (1d6 + 2) bludgeoning damage.

Bite (Spider Form only). Melee Weapon Attack: +5 to hit. Hit: 5 (1d6 + 2) piercing damage.

Change Shape (1/turn). The yochlol can polymorph into a form that resembles a female drow or giant spider, or back into its true form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.

Mist Form (1/turn). The yochlol transforms into toxic mist or reverts to its true form. Any equipment it is wearing or carrying is also transformed. It reverts to its true form if it dies.

While in mist form, the yochlol is incapacitated and can’t speak. It has a flying speed of 5 meters, can hover, and can pass through any space that isn’t airtight. It has advantage on Reflex and Fortitude saving throws, and it is immune to nonmagical damage.

While in mist form, the yochlol can enter a creature’s space and stop there. Each time that creature starts its turn with the yochlol in its space, the creature must succeed on a Difficulty 16 Fortitude saving throw or be poisoned until the start of its next turn. While poisoned in this way, the target is incapacitated.

Summon Demon (1/long rest). The yochlol has a 50 percent chance of summoning one yochlol. A summoned demon appears in an unoccupied space within 10 meters of the yochlol, acts as its ally, and can’t summon other demons. It remains for 1 minute, until it or the yochlol dies, or until the yochlol dismisses it on its turn (no action required).

As two actions, you can read the thoughts of certain creatures. When you cast the spell—and as two actions on each turn until the spell ends—you can focus your mind on a creature that you can touch or see within 5 meters of you. If the creature has an Intelligence of −4 or lower or doesn’t speak any language, the creature is unaffected.

You initially learn the surface thoughts of the creature—what is most on its mind in that moment. As two actions, you can either shift your attention to another creature’s thoughts or attempt to probe deeper into the same creature’s mind. If you probe deeper, the target must make a Will saving throw. If it fails, you gain insight into its reasoning (if any), its emotional state, and something that looms large in its mind (such as something it worries over, loves, or hates). If it succeeds, the spell ends. Either way, the target knows that you are probing into its mind, and unless you shift your attention to another creature’s thoughts, the creature can use an action on its turn to repeat the saving throw; if it succeeds, the spell ends.

Questions verbally directed at the target creature naturally shape the course of its thoughts, so this spell is particularly effective as part of an interrogation. You can also use this spell to detect the presence of thinking creatures you can’t see. When you cast the spell or as two actions during the duration, you can search for thoughts within 5 meters of you. The spell can penetrate barriers, but 60 centimeters of stone, 5 centimeters of any metal other than lead, or a thin sheet of lead blocks you. You can’t detect a creature with an Intelligence of 3 or lower or one that doesn’t speak any language.

Once you detect the presence of a creature in this way, you can read its thoughts for the rest of the duration as described above, even if you can’t see it, but it must still be within 5 meters of you.

Augment

You can expend 1 additional mana to plant an idea or memory in the creature’s mind. The creature must remain within 5 meters of you and you must focus on it for 1 minute. After 1 minute the creature must make a Will saving throw or you plant the idea or memory in the creature’s mind as if it were an organic thought or real memory. You choose whether the idea or memory is trivial (such as “I had porridge for breakfast” or “Ale is the worst”) or personality-defining (“I failed to save my village from orc marauders and am therefore a coward” or “Magic is a scourge, so I renounce it”). The idea or memory lasts for 4 hours for each mana expended to cast this spell.

concentration, 1 minute/mana

As two actions, you are surrounded by invisible necrotic spores in an aura shaped as a sphere. Until the spell ends, the aura moves with you, centered on you. An enemy creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Fortitude saving throw.

    A creature can make a Will saving throw at the end of each of its turns, ending the effect on itself on a success.

concentration, 1 minute/mana

As two actions, you take control of an animal that you can touch or see within 10 meters. The creature must make a Will saving throw, which it does with advantage if you or your companions are fighting it.

On a failure, it you gain control for the duration.

The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Each time the target takes damage, it makes a new Will saving throw against the spell. If the saving throw succeeds, the spell ends.

While you have control, you have a telepathic link with it as long as the two of you are on the same plane of existence. You can use this telepathic link to issue commands to the creature while you are conscious (no action required), which it does its best to obey. You can specify a simple and general course of action, such as “Attack that creature,” “Run over there,” or “Fetch that object.” If the creature completes the order and doesn’t receive further direction from you, it defends and preserves itself to the best of its ability.

You can use two actions to take total and precise control of the target. Until the end of your next turn, the creature takes only the actions you choose, and doesn’t do anything that you don’t allow it to do. During this time, you can also cause the creature to use a reaction, but this requires you to use your own reaction as well.

  • Humanoid. You can expend 1 additional mana to target a humanoid.

As two actions, you create a sphere of yellow, nauseating gas twice as big as normal centered on a point within 20 meters. The cloud spreads around corners, and its area is heavily obscured. The cloud lingers in the air for the duration.

A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Fortitude saving throw. If the creature doesn’t need to breathe or is immune to poison, the spell has no effect on it.

On a failure, it spends its actions that turn retching and reeling.

A moderate wind (at least 15 kilometers per hour) disperses the cloud after 4 rounds. A strong wind (at least 30 kilometers per hour) disperses it after 1 round.

concentration, 1 hour/mana

As two actions, you conjure a mass of thick, sticky webbing at a point of your choice within 10 meters. The webs fill a sphere from that point for the duration. The webs are difficult terrain and lightly obscure their area.

If the webs aren’t anchored between two solid masses (such as walls or trees) or layered across a floor, wall, or ceiling, the conjured web collapses on itself, and the spell ends at the start of your next turn. Webs layered over a flat surface have a depth of 1 meter.

A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Reflex saving throw.

On a failure, it is restrained as long as it remains in the webs or until it breaks free.

A creature restrained by the webs, or one that can touch the creature, can use an action to make a Brawn or Nimbleness check (its choice) against your spell save Difficulty. If it succeeds, it is no longer restrained.

The webs are flammable. Any 1-meter cube of webs exposed to fire burns away in 1 round, dealing 2d4 fire damage to any creature that starts its turn in the fire.
