SPECIAL TRAITS

  • Extraplanar Salvation. If damage reduces the keeper of madness to 0 hit points, it may attempt an Intelligence saving throw with a DC of 5 + the damage taken. On a success, the keeper of madness drops to 1 hit point and can use its reaction to cast plane shift on itself, traveling to a location of its choice on another plane of existence. This casting of plane shift can be negated by counterspell and any other effects that interfere with casting a spell.
  • Magic Resistance. The keeper of madness has advantage on saving throws against spells and other magical effects.
  • Innate Spellcasting. The keeper of madness is a 10th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 16, +8 to hit with spell attacks). The keeper of madness can cast the following spells innately, requiring no material components:

ACTIONS

  • Mental Breakdown. Melee Weapon Attack: +7 to hit, reach 5 ft., one stunned creature. Hit: The target takes 55 (10d10) psychic damage; if this damage reduces the target to 0 hit points, the target remains unconscious for 1d4 hours, regardless of any healing received. When the target awakens, it is afflicted by madness, giving it disadvantage on all ability checks and saving throws with Intelligence, Wisdom, or Charisma. The target also gains the following flaw: “I never feel safe, not even in my thoughts.” This effect is considered a curse, and can be removed by any effects that remove curses.
  • Touch of Insanity. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) psychic damage. If the target is a humanoid, it must succeed on a DC 16 Intelligence saving throw or become stunned. Stunned creatures can repeat the saving throw at the end of each of their turns, ending the effect on a success. Lesser restoration or similar, more powerful spells will also remove this effect.
  • Wave of Madness (Recharge 6). The keeper of madness magically projects a cone 60 feet in length. Each creature in the area must attempt a DC 16 Wisdom saving throw, taking 36 (8d8) psychic damage on a failure and gaining one random effect from the Madness: Short-Term table. On a success, the damage is halved and the target does not go mad. This is considered a charm effect.

I should remain near it.” Flaw: “Anyone who tries to cheer me up just can’t see the truth. I must convince them the world is terrible.”
3 Anger Flaw: “Everything is an insult; some are just hidden behind false kindness.” Bond: “I’m going to punch the next person who disagrees with me.” Ideal: “Every dispute should be settled with violence. Last one conscious must be right.”
