Conductive Body. Whenever the golem is subjected to lightning damage, it takes no damage. Instead, its weapon attacks deal an extra 22 (4d10) lightning damage until the end of its next turn. Also until the end of the golem’s next turn, any creature that touches it or hits it with a melee attack while within 10 feet of it takes 22 (4d10) lightning damage.

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

Super Heated. Whenever the golem is subjected to cold damage, it takes no damage. Instead, the golem releases a wave of intense heat in a 20-foot radius sphere centered on itself. All creatures within this area must make a DC 25 Constitution saving throw or take 21 (6d6) fire damage, or half as much on a successful one.

Limited Magic Immunity. The golem can't be affected or detected by spells of 6th level or lower unless it wishes to be. It has advantage on saving throws against all other spells and magical effects.

Crushing Trample. The golem can move through the space of a creature that is medium or smaller. A creature whose space the golem enters for the first time on a turn must make a DC 25 Dexterity saving throw, taking 88 (16d10) bludgeoning damage on a failed save, or half as much on a successful one.

Siege Monster. The golem deals double damage to objects and structures.

Adamantine Plating. Any critical hit against the golem becomes a normal hit.

Immutable Form. The golem is immune to any spell or effect that would alter its form.

Magic Weapons. The golem's weapon attacks are magical.

Multiattack. The golem makes two melee attacks.

Slam. Melee Weapon Attack: +18 to hit, reach 10 ft., one target. Hit: 43 (6d10 + 10) bludgeoning damage.

Stomp. Melee Weapon Attack: +18 to hit, reach 5 ft., one target. Hit: 54 (8d10 + 10) bludgeoning damage.

Paralyzing Breath (Recharge 6). The golem exhales paralyzing gas in a 60-foot cone. Each creature in that area must succeed on a DC 25 Constitution saving throw or be paralyzed 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.
