  • Fire Absorption. Whenever the golem is subjected to fire damage, it takes no damage and instead regains a number of hit points equal to the fire damage dealt.
  • Immutable Form. The golem is immune to any spell or effect that would alter its form.
  • Magic Resistance. The golem has advantage on saving throws against spells and other magical effects.
  • Magic Weapons. The golem’s weapon attacks are magical.

    Psychic Amplification. Each time a creature within 30 feet of the golem casts a divination or enchantment spell, they can cast it without somatic and verbal components. Creatures within 30 feet also have advantage on saving throws to maintain concentration on such spells.

    Receptacle. A crystal golem can be possessed (such as by a ghost or the magic jar spell) as though it were a creature of the the humanoid type, though it has advantage on saving throws to resist. The golem does not resist these effects if they come from its creator or targets designated by its creator.


  • Multiattack. The golem makes two slam attacks.
  • Slam. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage, plus (1d8) force damage.
  • Psychic Blast (Recharge 4-6). The golem chooses one creature within 30 feet that it can see. The target must succeed on a DC 14 Wisdom saving throw. The target takes 45 (10d8) psychic damage on a failed saving throw, or half as much damage on a success. If the target fails the saving throw and the damage reduces the target to 0 hit points, the target’s head explodes, killing the target (if the target needs a head to survive), and showering nearby creatures with debris. Creatures within a 10-foot radius of the debris must succeed on a DC 15 Dexterity saving throw, taking 7 (2d6) slashing damage on a failed saving throw and half as much damage on a success.


Crystal golems are rough-cut humanoid constructs hewn from spars and blocks of bluish crystal.

Shining with an inner light, crystal golems cannot speak but emit a constant hum of psychic energy. A typical crystal golem is 10 feet tall and weighs over 1,800 pounds.
