Trait
Regeneration Custom
The ooze regains 10 hit points at the start of its turn. If it takes radiant damage or damage from a magic weapon, this trait doesn't function at the start of its next turn. The ooze dies only if it starts its turn with 0 hit points and doesn't regenerate.

Regeneration. Custom regeneration mechanic; radiant or magic weapon damage suppresses it.

Pseudopod

Action
Poisoned Condition
Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 13 (3d6+3) bludgeoning damage plus 10 (3d6) acid damage, and the target must succeed on a DC 14 Constitution saving throw or be poisoned for 1 minute. The poisoned target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Engulf

Action
Blinded Condition
Restrained Condition
The ooze moves up to its speed. While doing so, it can enter a Large or smaller creature's space. When the ooze enters a creature's space, the creature must succeed on a DC 14 Dexterity saving throw or be engulfed by the ooze. An engulfed creature is blinded, restrained, and has total cover against attacks and other effects outside the ooze. An engulfed creature takes 10 (3d6) acid damage plus 7 (2d6) psychic damage at the start of each of the ooze's turns. The ooze can hold only one Large creature or up to two Medium or smaller creatures at a time.

Psychic Lash (Recharge 5-6)

Action
Incapacitated Condition
The ooze emits a burst of psychic energy in a 30-foot cone. Each creature in that cone must succeed on a DC 14 Intelligence saving throw or take 21 (6d6) psychic damage and be incapacitated until the end of its next turn. On a success, a creature takes half damage and isn't incapacitated.

Mindflare Burst

Reaction
Frightened Condition
When the ooze takes damage from a creature within 30 feet, it can force that creature to make a DC 14 Wisdom saving throw. On a failure, the creature takes 9 (2d8) psychic damage and is frightened of the ooze until the end of its next turn.

Combat Behavior

Tactics


• The mindflare ooze uses its Aura of Mindfire to soften up enemies, then engulfs a target to isolate it from its allies.
• It prefers to attack with its Pseudopod, poisoning targets to make them easier to engulf.
• If surrounded, it uses Psychic Lash to incapacitate multiple foes, then retreats or engulfs a vulnerable target.
• It uses its Mindflare Burst reaction to punish enemies that attack it, especially those with low Wisdom saves.

Monster Description

A mindflare ooze is a bizarre fusion of a gelatinous cube, a mind flayer's psychic energy, and demonic essence. It appears as a translucent, quivering mass of acidic slime with a faint, roiling purple light at its core. It drifts through dungeons and caverns, its mind-altering aura driving lesser creatures mad. It is often found in areas corrupted by demonic influence or where psychic energy is strong.

History

Mindflare oozes are unnatural creations, born from the chaotic intersection of an abyssal rift and a mind flayer's psionic experiments. They are rare and feared by even the most hardened adventurers.
