Juiblex

Lair Actions

Source: Mordenkainen Presents: Monsters of the Multiverse

On initiative count 20 (losing initiative ties), Juiblex can take one of the following lair actions; it can’t take the same lair action two rounds in a row:

  • Green Slime. A green slime (see the “Dungeon Master’s Guide”) appears on a spot on the ceiling that Juiblex chooses within the lair. The slime disintegrates after 1 hour.

  • Slippery Slime. Juiblex slimes a square area of ground it can see within the lair. The area can be up to 10 feet on a side. When the slime appears, each creature on it must succeed on a DC 21 Dexterity saving throw or fall prone and slide 10 feet in a random direction determined by a d8 roll. When a creature enters the area for the first time on a turn or ends its turn there, that creature must make the same save.

    The slime lasts for 1 hour or until it is burned away with fire. If the slime is set on fire, it burns away after 1 round. Any creature that starts its turn in the burning slime takes 22 (4d10) fire damage.

  • Sticky Slime. Juiblex slimes a square area of ground it can see within the lair. The area can be up to 10 feet on a side. When the slime appears, each creature in that area must succeed on a DC 21 Strength saving throw or become restrained. When a creature enters the area for the first time on a turn or ends its turn there, that creature must make the same save.

    A restrained creature is stuck as long as it remains in the slimy area or until it breaks free. The restrained creature, or another creature that can reach it, can use its action to try to break free and must succeed on a DC 21 Strength check. The slime lasts for 1 hour or until it is burned away with fire. If the slime is set on fire, it burns away after 1 round. Any creature that starts its turn in the burning slime takes 22 (4d10) fire damage.

Regional Effects

Source: Mordenkainen Presents: Monsters of the Multiverse

The region containing Juiblex’s lair is warped by its magic, creating one or more of the following effects:

  • Acidic Water. Small bodies of water, such as ponds or wells, within 1 mile of the lair turn highly acidic, corroding any object that touches them.
  • Corrupted Nature. Within 6 miles of the lair, all Wisdom (Medicine) and Wisdom (Survival) checks have disadvantage.
  • Slime. Surfaces within 6 miles of the lair are frequently covered by a thin film of slime, which is slick and sticks to anything that touches it.

If Juiblex dies, these effects fade over the course of 1d10 days.
