Special Traits

  • Amphibious. The veiled master can breathe air and water.
  • Mucous Cloud. While underwater, the veiled master is surrounded by transformative mucus. A creature that touches the veiled master or that hits it with a melee attack while within 5 feet of it must make a DC 20 Constitution saving throw. On a failure, the creature is diseased for 1d4 hours. The diseased creature can breathe only underwater.
  • Probing Telepathy. If a creature communicates telepathically with the veiled master, the veiled master learns the creature’s greatest desires and darkest fears if the veiled master can see the creature. Additionally, for each minute of continued telepathic communication, the veiled master can experience one of that creature’s memories.
  • Innate Spellcasting. A veiled master’s spell casting ability is Charisma (spell save DC 19). It can innately cast the following spells, requiring no material components:


  • Multiattack. The veiled master makes three tentacle attacks.
  • Tentacle. Melee Weapon Attack: +9 to hit, 20 ft. reach, one target. Hit: 13 (2d8 + 4) bludgeoning damage plus 21 (6d6) lightning damage. If the target is a creature, it must succeed on a DC 20 Constitution saving throw or become diseased. The disease has no effect for 1 minute and can be removed by any magic that cures disease. After 1 minute, the diseased creature’s skin becomes translucent and slimy, the creature can’t regain hit points unless it is underwater, and the disease can be removed only by heal or another disease-curing spell of 6th level or higher. When the creature is outside a body of water, it takes 6 (1d12) acid damage every 10 minutes unless moisture is applied to the skin before 10 minutes have passed.
  • Bite. Melee Weapon Attack: +9 to hit, 10 ft. reach, one target. Hit: 15 (2d10 + 4) piercing damage. If the target is a creature, it must succeed on a DC 17 Wisdom saving throw or suffer an additional 27 (6d6 + 6) psychic damage as the veiled master consumes its memories. The target’s hit point maximum is reduced by an amount equal to the psychic damage taken, and the veiled master regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. If the target’s hit point maximum is reduced to 0, it remains alive and conscious and is treated as though it had 1 hit point, but it becomes a mindless slave of the veiled master, as though affected by the veiled master’s enslave ability.
  • Enslave (3/day). The veiled master targets one creature it can see within 60 feet of it. The target must succeed on a DC 19 Wisdom saving throw or be magically charmed by the veiled master until the veiled master dies or until it is on a different plane of existence from the target. The charmed target is under the veiled master’s control and can’t take reactions, and the veiled master and the target can communicate telepathically with each other over any distance. Whenever the charmed target takes damage, the target can repeat the saving throw. On a success, the effect ends. No more than once every 24 hours, the target can also repeat the saving throw when it is at least 1 mile away from the veiled master.

Legendary Actions

The veiled master can take 4 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The veiled master regains spent legendary actions at the start of its turn.

  • Detect. The veiled master makes a Wisdom (Perception) check.
  • Mental Assault. The veiled master bombards the mind of a single creature within 60 feet with psychic static. That creature has disadvantage on all d20 rolls it makes until the beginning of its next turn.
  • Psychic Drain (Costs 2 actions). One creature charmed by the veiled master takes 21 (6d6) psychic damage, and the veiled master regains hit points equal to the damage the creature takes.


As befits their hideous primeval appearance, the hermaphroditic aboleths are among the world’s oldest forms of life. Ancient even when the gods first turned their eyes to the Material Plane, the aboleths have always existed apart from other mortal life, alien and cold and endlessly plotting. They once ruled the world with vast empires, and today view most other forms of life as either food or slaves-and sometimes both. They disdain the gods and see themselves as the true masters of creation. An aboleth is 25 feet long and weighs 6,500 pounds.

In the darkest reaches of the sea, aboleths still dwell in grotesque cities built in nauseating and cyclopean styles. There they are served by countless slaves culled from every nation, air-breathing and aquatic alike, although the air-breathing slaves are doubly bound by magic and the need to constantly replenish their water-breathing ability via the excretions of their aboleth masters. Lone aboleths are often advance scouts for these hidden cities, seeking out new slaves.
