Another monster stolen from Sekiro – the Immortal Monk. My PCs bypassed these as well as one of my players had played Sekiro and when he saw a giant centipede burst out of a monk statue he told the party to run. Built of a flesh golem.

Berserk. Whenever the infested statue starts its turn with 40 hit points or fewer, roll a d6. On a 6, it goes berserk. On each of its turns while berserk, the infested statue attacks the nearest creature it can see. If no creature is near enough to move to and attack, the infested statue attacks an object, with preference for an object smaller than itself. Once the infested statue goes berserk, it continues to do so until it is destroyed or regains all its hit points.The infested statue’s creator, if within 60 feet of the berserk infested statue, can try to calm it by speaking firmly and persuasively. The infested statue must be able to hear its creator, who must take an action to make a DC 15 Charisma (Persuasion) check. If the check succeeds, the infested statue ceases being berserk. If it takes damage while still at 40 hit points or fewer, the infested statue might go berserk again.
Aversion of Fire. If the infested statue takes fire damage, it has disadvantage on attack rolls and ability checks until the end of its next turn.
Immutable Form. The infested statue is immune to any spell or effect that would alter its form.
Lightning Absorption. Whenever the infested statue is subjected to lightning damage, it takes no damage and instead regains a number of hit points equal to the lightning damage dealt.
Magic Resistance. The infested statue has advantage on saving throws against spells and other magical effects.
Magic Weapons. The infested statue’s weapon attacks are magical.
Immortal. The infested statue cannot be killed except by the use of a special weapon – for example a mortal blade or an honourable weapon. It collapses when reduced to 0 hit points and then spends a round incapacitated. At the start of its next round, so long as it took no damage, it gets up with full hit points.
Statue Defense. The infested statue withdraws into its statue. Until it emerges, it gains a +4 bonus to AC and has advantage on Strength and Constitution saving throws. While in its statue, the infested statue speed is 0 and can’t increase, it has disadvantage on Dexterity saving throws, it can’t take reactions, and the only action it can take is a bonus action to emerge. While in its statue the centipede regains 13 (2d8 + 4) hit points each round.
ACTIONS
Multiattack. The infested statue makes two centipede bite attacks.
Centipede bite. Melee Weapon Attack: +7 to hit, reach 15 ft., one target.
Hit: 13 (2d8 + 4) bludgeoning damage, and the target must succeed on a DC 15 Constitution saving throw or take 10 (3d6) poison damage. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.
Constrict. Melee Weapon Attack: +7 to hit, reach 15 ft., one creature.
Hit: 13 (3d8 + 4) bludgeoning damage, and the target is grappled (escape DC 14). Until this grapple ends, the creature is restrained, and the centipede can’t constrict another target. While constricting it losses its Multiattack option but automatically does 13 (3d8 + 4) bludgeoning damage at the start of its turn to the constricted target.
REACTIONS
Bleeding Swarm (1/Day). Once hit by an attack, not only does the statue bleed but the wound bleeds hundreds of centipedes – Swarm of Centipedes appears within 5 feet of the infested statue.
TACTICS
The infested statue will attack anyone that comes within reach, but unless it is being attacked at range, it does not move depending on its reach and “Statue Defense” ability.
