  • Immutable Form. The colossus is immune to any spell or effect that would alter its form.
  • Light Absorption. Whenever the colossus is subjected to radiant damage, it takes no damage and instead regains a number of hit points equal to the radiant damage dealt.
  • Magic Resistance. The colossus has advantage on saving throws against spells and other magical effects.
  • Magic Weapons. The colossus’s weapon attacks are magical.
  • Portal Crystal. The crystal’s base is 10 feet wide and 10 feet long, and it is 40 feet tall. To activate the crystal, the colossus needs to place it in an unoccupied space and work 1 minute on the crystal without any interruptions. Once it’s activated, it connects to all other active crystal portals. Only angels can use these portals to travel between the portal network and an angel can bring one willing creature with them.


  • Multiattack. The colossus makes two melee attacks.
  • Slam. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 31 (5d8 + 9) bludgeoning damage.
  • Radiant Flash (Recharge 6). The colossus focuses light using its body and releases it in a blinding flash. Each creature within 30 feet must make a DC 20 Constitution saving throw. A creature is blinded and takes 45 (10d8) radiant damage on a failed save, or isn’t blinded and takes half as much damage on a successful one.


These heavenly constructs infused with angelic essence named glass colossi are among the most resilient angels. When heaven is in the throes of a massive battle, a glass colossus is almost always the first on the battlefield and their enormous figures are almost always horrifying to opponents.

Crystal Carrier. Every glass colossus carries a crystal that is almost as large as they are. Their main duty is to protect the crystal and place it somewhere according to the instructions of their superiors. The crystal acts as a portal for the armies of heaven to join the fight.

Divine Construct. A glass colossus doesn’t require air, food, drink, or sleep. It can’t take short or long rests.

Obedience. A glass colossus obeys angels’ commands to the best of its ability. If it is left without commands or can’t fulfill them, it guards its position and waits for further instruction. A glass colossus can’t think or act on its own or for itself. Though it understands its commands perfectly, it has no grasp of language beyond that understanding, and can’t be reasoned with or tricked with words.
