The Altered World Experience
- Grapple.
1d4. Instead of dealing damage, on a 2-3, the target is grappled. On a 4, the target is restrained.
The Mind Killer can move through a space as narrow as 1 inch wide without squeezing.
The mind killer is unaffected by psionic powers unless it wishes to be.
- •Claws.2d8+9.
If the target is medium or smaller, they are grappled. Escape DC 12.
- •Concealing Strike.3d6+3.
Psychic damage. Range 6. Mind killer is invisible to the target until the end of the mind killer's next turn.
- •Mindwipe.10.
A Humanoid grappled by the mind killer must succeed on a DC 12 Strength saving throw or the mind killer enters the Humanoid's body. While inside a Humanoid, the mind killer has total cover against attacks and other effects originating outside the Humanoid, and the only action the mind killer can take is to leave the body, exiting in an unoccupied space within 5 feet of the body.
When a Humanoid ends their turn with the mind killer inside of them, they must succeed on a DC 13Constitution saving throw or take 10 necrotic damage. If the Humanoid is reduced to 0 hit points, they die and the mind killer takes over the body, which regains hit points equal to the Humanoid's hit point maximum. The mind killer retains their Intelligence, Wisdom, and Charisma scores, their understanding of Deep Speech and Undercommon, and their telepathy. They otherwise adopt the target's statistics and can take the actions the creature could take. They know everything the creature knew, including spells, class features, traits, and languages. If the body is reduced to 0 hit points after the mind killer takes control, the mind killer must leave it.
A creature wielding a sharp tool or weapon within reach of a Humanoid host or body with a mind killer inside can use an action to attempt to remove the mind killer, making an attack roll against the Humanoid's AC if the host is unwilling. On a hit, the creature deals 11 (2d10) slashing damage to the host and must make a DC 15 Wisdom (Medicine) check. On a successful check, the creature cuts the mind killer out of the host. On a faiIed check, if this slashing damage reduced the host to 0 hit points, the mind killer kills the host; otherwise, there is no effect.
The mind flayer doesn’t require air, food, or sleep.
While in sunlight, the mind flayer has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
The mind flayer can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check

- •Disrupt Psyche (1 use).
The mind flayer magically emits psionic energy in a 30-foot-radius sphere centered on itself. Each creature in that area must succeed on a DC 15 Intelligence saving throw or be dazed for 1 minute. The dazed creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

If no thralls remain, psychic echoes of their minds cause a disembodied shriek; each PC must succeed on a DC 13 Wisdom save or have disadvantage on their next saving throw.
- [ ] Whispering Chorus. The lair fills with maddening whispers. Until the next round, all creatures that attempt to cast a spell within the lair must succeed on a DC 13 Intelligence saving throw or the spell fails (the slot isn’t lost).

Before the beginning of the Players' turn, Borogeaa takes a lair action to cause one of the following effects; Borogeaa can’t use the same effect two rounds in a row:
-
[ ] Floor of Ice. The icy floor of the chamber becomes slick and slippery, transforming into difficult terrain. A creature moving across the floor must succeed on a DC 13 DEX save or fall prone. The effect ends when Borogeaa takes her next Lair Action.
-
[ ] Frozen Servants. 3 ice mephit minions coalesce out of the air. These remain until destroyed, but have a maximum number of 3 on the field at any one time.
-
[ ] Ice Armor. Hoarfrost gathers on Borogeaa’s torso and limbs, solidifying into a suit of armor made of ice that grants her Medium Armor. The armor melts if Borogeaa takes more than 30 fire damage. Otherwise, it disappears when Borogeaa takes her next Lair Action.
- •Freezing Death.
(1 time use, recharge on Bloodied). With a touch, Borogeaa deals 4d8 cold damage plus 4d8 necrotic damage. If this damage would reduce the target to 0 hit points, the target drops to 1 hit point instead and has the petrified condition, turning into a frozen statue.
If the statue takes bludgeoning damage, it shatters, killing the frozen creature. If the statue would take fire damage, it instead takes no damage and thaws, ending the petrification.

At 0 HP Borogeaa is dying. If she takes 50 more damage she dies. Immediately after a creature Borogeaa completes a turn in which they damaged her, she momentarily dissolves into a blizzard, magically teleporting to an unoccupied space she can see within 30 feet of herself and makes a Icy Axe attack. This is in place of her normal action, not in addition to it, and the teleportation does not provoke opportunity attacks.
