Chardalyn Golem

Radiant Absorption. Whenever the golem is subjected to radiant damage, it takes no damage and instead regains a number of hit points equal to the radiant 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.

Multiattack. The golem makes two melee attacks.

Slam. Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 20 (3d8 + 7) bludgeoning damage.

Sword. Melee Weapon Attack: +13 to hit, reach 10 ft., one target, and the target must succeed on a DC 15 Constitution saving throw or be poisoned until the end of it's next turn. Hit: 23 (3d10 + 7) slashing damage.

Malevolent Presence. Any creature with an Intelligence of 4 or more that is within 30 feet of the Golem must succeed on a DC 15 Intelligence saving throw or be charmed by it 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 Golem's Malevolent Presence for the next 24 hours. A creature charmed in this way fixates on another creature or object that the Golem mentally chooses and must, on each of its turns, move as close as it can to that target and use its action to make a melee attack against it. If the Golem doesn’t choose a target, the charmed creature can act normally on its turn.

Radiant Breath. (Recharge 6). The golem exhales radiant light in a 15-foot by 5-foot line. Each creature in that area must make a DC 19 Dexterity saving throw, taking 45 (10d8) radiant damage on a failed save, or half as much damage on a successful one.

Long Stride.  Creature can use a bonus action to move 30 feet.

Chardalyn Shield. Once per round the Chardalyn Golem can use it's reaction to unfold a chardalyn shield, raising it's AC by 2, it cannot do this again until it's next turn.
