Fire Absorption. Whenever Langres 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. Langres is immune to any spell or effect that would alter its form.

Magic Resistance. Langres has advantage on saving throws against spells and other magical effects.

Aura of Rot. Within a 60 ft area of Langres all objects made of Wood or Textile starts to rot and dissapear within a round, Magical Items won't dissapear but are unusable within the area.

Multiattack. Langres makes two melee attacks.

Slam. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 20 (3d8 + 7) bludgeoning damage.

Disintegration Ray (Recharge 6). Choosing a target within 120 ft Langres fires a ray from its left hand. If the target is a creature, it must succeed on a DC 16 Dexterity saving throw or take 55 (10d10) force damage. If this damage reduces the creature to 0 hit points, its body becomes a pile of fine gray dust, with all it has equipped dropped. If the target is a Large or smaller nonmagical object or creation of magical force, made of organic material, it is disintegrated without a saving throw. If the target is a Huge or larger object or creation of magical force, this ray disintegrates a 10-foot cube of it. If the target is made of inorganic material it has no effect on it.

Poison Breath (Recharge 5-6). Langres exhales poisonous gas in a 15-foot cone. Each creature in that area must make a DC 19 Constitution saving throw, taking 45 (10d8) poison damage on a failed save, or half as much damage on a successful one.

Reflect All. As a reaction Langres can deal equal damage to an enemy to that of one instance of damage dealt to it.
