# 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](/Rules/Source/traps-hazards/green-slime-xdmg.md) (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](/Rules/Source/conditions.md#Prone) and slide 10 feet in a random direction determined by a `dice:d8|noform|noparens|avg` (`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 `dice:4d10|noform|noparens|avg|text(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](/Rules/Source/conditions.md#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](/Rules/Source/conditions.md#Restrained) creature is stuck as long as it remains in the slimy area or until it breaks free. The [restrained](/Rules/Source/conditions.md#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 `dice:4d10|noform|noparens|avg|text(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](/Rules/Source/skills.md#Medicine)) and Wisdom ([Survival](/Rules/Source/skills.md#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 `dice:1d10|noform|noparens|avg` (`1d10`) days.
