  • Devil’s Sight. Magical darkness doesn’t impede the flayer’s darkvision.
  • Magic Resistance. The flayer devil has advantage on saving throws against spells and other magical effects.
  • Flensing. On a natural 20, the horned and serrated claws and fists of the flayer tears flesh from bone, dealing (5d8) necrotic damage to its opponent in addition to critical damage from its claw attack.
  • Regeneration. The flayer regains 10 hit points at the start of its turn. If the flayer takes damage from a silvered weapon, this trait doesn’t function at the start of the flayer’s next turn. The flayer is destroyed only if it starts its turn with 0 hit points and doesn’t regenerate.
  • Innate Spellcasting. The flayer’s innate spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). It can cast the following spells, requiring no material components:


  • Multiattack. The flayer makes one Bite attack and two Claw attacks.
  • Bite. Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 16 (2d8 + 7) piercing damage.
  • Claw. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 11 (1d8 + 7) slashing damage and 7 (2d6) necrotic damage.
  • Unholy Burst (recharge 5-6). A 30-foot cube of hellish brimstone bursts forth from the skin of the flayer, causing those within the wave to succeed DC 19 Constitution save or gain the poisoned condition for one hour.


Flayer devils are musclebound brutes with thick crimson skin that stinks of soot and brimstone. Their beastly horned head features a wide mouth filled with broken, rotting yellow fangs, and their eyes glow like molten metal. Their long arms end in horned fists and serrated hook-like claws. Flayers stand 13 feet tall and weigh more than 800 pounds.

When the barons and dukes of Hell need a brute to do a brute’s job, they often call upon the legions of marzachs. These deadly giants of Hell use their horned fists and ripping claws to tear the flesh of their enemies to ribbons. Born from a choir of angelic warriors who were turned by the infernal lords, they have the power to emit an unholy burst of brimstone that sickens those around them.
