SPECIAL TRAITS

  • Amorphous. The sarcophagus slime can move through a space as narrow as 1 inch wide without squeezing.
  • Undead Nature. The sarcophagus slime doesn’t require air, food, drink, or sleep.

ACTIONS

  • Multiattack. The sarcophagus slime can use its Frightful Presence. It then makes two Slam attacks. It can replace one Slam attack with a use of Corrupting Gaze.
  • Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage plus 9 (2d8) acid damage.
  • Corrupting Gaze. One creature the sarcophagus slime can see within 30 feet of it must make a DC 15 Constitution saving throw, taking 18 (4d8) necrotic damage on a failed save, or half as much damage on a successful one. The target’s hp maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hp maximum to 0. A Humanoid slain by this effect rises 24 hours later as a sarcophagus slime, unless the Humanoid is restored to life or its body is destroyed.
  • Frightful Presence. Each creature of the sarcophagus slime’s choice that is within 60 feet of the sarcophagus slime and aware of it must succeed on a DC 15 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the sarcophagus slime’s Frightful Presence for the next 24 hours.

ABOUT

The sarcophagus opens to reveal an eerie, scintillating light.

Wisps of gelid amber ectoplasm undulate outward from a quivering mass with a blackened skull at its center.

Vigilant Slime. Sarcophagus slimes are amorphous undead guardians placed in the tombs of the powerful to guard them and to wreak terrible vengeance on would-be defilers of the ancient crypts. The slimes seethe with baleful energy, and their blackened skulls retain a simple watchfulness.

Muddled Origins. Many sages speculate that the first sarcophagus slime was spawned accidentally, in a mummy creation ritual that gave life to the congealed contents of canopic jars rather than the intended, mummified body. Others maintain sarcophagus slime was created by a powerful necromancer-pharaoh bent on formulating the perfect alchemical sentry to guard his crypt.

Death to Tomb Robbers. These ectoplasmic slimes are the bane of burglars and a constant danger for excavators and antiquarians exploring ruins or tombs. The rituals for their creation have not been entirely lost; modern necromancers still create these undead abominations for their own fell purposes, and tomb robbers are turned into slimes if they lack proper caution.
