Special Traits

  • Immutable Form. The jade colossus is immune to any spell or effect that would alter its form.
  • Magic Resistance. The jade colossus has advantage on saving throws against spell and other magical effects.
  • Magic Weapons. The jade colossus’ weapon attacks are magical.
  • Light Reflection. Any creature looking directly at the jade colossus while the colossus is in bright light must make a DC 12 Constitution saving throw or be blinded for 1 minute. Additionally, attacks against the colossus are made with disadvantage, and undead take 22 (4d10) radiant damage if they start their turn within 60 feet of the colossus.


  • Multiattack. The jade colossus makes two slam attacks.
  • Slam. Melee Weapon Attack: +15 to hit, reach 20 ft., one target. Hit: 36 (5d10 + 9) bludgeoning damage.
  • Jade Blast (Recharge 5-6). The jade colossus unleashes a blast of green energy in a 60-foot cone. Each creature in that area must make a DC 18 Dexterity saving throw, taking 56 (16d6) force damage on a failed save, or half as much damage on a successful one. Additionally, the creature magically begins to turn to jade and is restrained. The restrained target must repeat the saving throw at the end of its next turn. On a success, the effect ends on the target. On a failure, the target is petrified until freed by a greater restoration spell or other magic.


This massive automaton stands five times as tall as a normal human and resembles a gigantic humanoid carved of smooth green stone.

The jade colossus was first seen dominating the skyline over the City of Brass, its massive form reflecting the light from the ever-burning fires of the city. Since that time, rumors of these creatures moving across the Material Plane have been heard in taverns and inns.

Jade colossi are massive constructs built by powerful spellcasters to do their bidding; typically for protection or to wage war against an archrival.

A jade colossus pummels a foe with its hardened fists; dealing massive amounts of damage with every successful strike. It almost always opens combat with its breath weapon.

A typical jade colossus stands 35 feet tall and weighs about 60,000 pounds. (The jade colossus spotted in the City of Brass is thought to be over 50 feet tall and weigh in excess of 100,000 pounds.)

Sages speak of a jade colossus located in the City of Brass that has the Ruby Star of Law (a gem of inestimable value) embedded in its forehead. The Jade Guardian (as it is known in the city) is an advanced jade colossus with the following additional ability:

  • Energy Ray. Once per round as a bonus action, the Jade Guardian can fire a ray to a range of 200 feet. Genies hit by this ray must make a successful DC 18 Constitution saving throw or take 17 (7d4) points of Constitution damage. On a successful save, the genie takes half damage. Other creatures are affected as follows: Lawful creatures suffer two levels of exhaustion. Non-lawful creatures take 28 (8d6) force damage and are stunned for 1 minute.

Should the Ruby Star of Law ever be claimed as a magic item, treat it as a minor artifact that allows use of the energy ray ability indicated above up to 3/day, save that it requires a standard action to activate.
