Special Traits

• Amorphous. A dykath can move through a space as narrow as 2 inches wide without squeezing.
• Innate Spellcasting. A dykath’s innate spellcasting ability is Intelligence (spell save DC 18). It can innately cast the following spells, requiring no components:
  • At will: detect thoughts
  • 3/day each: charm monster, dispel magic, dominate person, dream, suggestion
  • 1/day each: compulsion, confusion, feeblemind, major image, modify memory, mirage arcane, phantasmal killer, plane shift (self only, can’t use)
• Fear Aura. A dykath emits a constant aura of fear in a 60-foot radius around him. A creature within this area of effect that can see Dykath must make a DC 14 Wisdom saving throw or become frightened for 1 minute. A creature can attempt a new save at the end of each of its turns, with success ending the effect on itself. Once a creature succeeds at this save, it cannot be affected by a dykath’s fear aura again for 24 hours.
• Immutable Form. A dykath is immune to any spell or effect that would alter its form.
• Magic Resistance. A dykath has advantage on saving throws against spells and other magical effects.
• Magic Weapons. A dykath’s weapon attacks are magical.
• Nightmare Slave. A dykath targets a living creature frightened by its fear aura within 30 feet of it. As a bonus action, a dykath can cast dominate person against the charmed creature. If the target fails its saving throw to resist this spell, it becomes permanently in thrall to a dykath. Dispel magic, wish, or similar magic can break this domination. Otherwise, the dominated creature can attempt a new saving throw following each long rest, ending the domination on itself with a success. If it fails three such consecutive saving throws, only dispel magic or similar spells can end the effect.
• No Breath. A dykath does not need to breathe.
• Wind Walk. As a bonus action, a dykath transforms into a gaseous form as if he had cast wind walk. It can end this effect and solidify as a bonus action.

Actions

• Multiattack. A dykath makes two claw attacks and two tentacle attacks.
• Claw. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 15 (2d8 + 6) piercing damage.
• Tentacle. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) bludgeoning damage. If a dykath hits a target with two tentacle attacks on the same turn, it does an additional 14 (4d6) bludgeoning damage.
