Aegian Sentinel (5e Creature)
From D&D Wiki
Medium construct, unaligned
Damage Immunities poison, psychic
Immutable Form. The sentinel is immune to any spell or effect that would alter its form.
Multiattack. The sentinel makes three claw attacks. It can substitute one of these attacks with a light beam.
Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage.
Light Beam. The sentinel fires a beam of bright golden light at one creature it can see within 20 feet. The creature must make a DC 10 Constitution saving throw, taking 13 (3d8) radiant damage on a failed save, or half as much damage on a successful one.
A skeletal figure made of ancient metal and covered with plates of mysterious ivory white steel, accented with intricate gold swirls. The sentinel waits inside its master's tomb in limbo, always watching, restlessly waiting for some unfortunate trespasser to come into its grasp, powered by a mystical golden light within that allows to march on—centuries and centuries after the last memories of the ones who created fade.
