Working name at the moment, supposed to a medium sized constructlike undead that it incredibly resilient and hard to kill, especially in large numbers. Was interested what people think, as well as what level an encounter some might think these would be.

Plague Construct

Hit Points 38 (4d12 + 12)
Speed 20 ft.
STR 16 (+3) DEX 10 (+0) CON 16 (+3) INT 3 (-4) WIS 6 (-2) CHA 5 (-3)
Saving Throws: Wis +0
Skills: Athletics +5
Damage Resistances: acid; bludgeoning, piercing, and slashing from nonmagical weapons that aren't adamantine
Damage Immunities: necrotic, psychic, poison
Condition Immunities: charmed, exhaustion, frightened, petrified, poisoned
Senses darkvision 60 ft., blindsight 30ft., passive Perception 8

Features
Immutable Form. The plague construct is immune to any spell or effect that would alter its form.
Regeneration. The plague construct regains 10 hit points at the start of its turn. If the plague construct takes radiant damage, this trait doesn't function at the start of the plague constructs's next turn. The plague construct dies only if it starts its turn with 0 hit points and doesn't regenerate.
Plague Fortitude. If damage reduces the plague construct to 0 hit points, it must make a Constitution saving throw with a DC equal to the damage taken, unless the damage is radiant or from a critical hit. On a success, the plague construct drops to 1 hit point instead.
Death Burst. When the plague construct dies, it explodes in a burst of dark energy. Each creature within 10 feet of it must make a DC 11 Dexterity saving throw, taking 7 (2d6) necrotic damage on a failed save, or half as much damage on a successful one.
Loathsome Limbs. Whenever the plague construct takes at least 15 slashing damage at one time, roll a d20 to determine what else happens to it:
1-10: Nothing else happens.
11- 17: One arm is severed from the plague construct if it has any arms left.
18-19: One leg is severed from the plague construct if it has any legs left.
20: The plague construct is decapitated, but the plague construct dies only if it can't regenerate. If it dies, so does the severed head.
If the the plague construct finishes a short or long rest without reattaching a severed limb or head, the part regrows. At that point, the severed part dies.
Until then, a severed part acts on the plague construct's initiative and has its own action and movement. A severed part has AC 13, 10 hit points, and the plague constructs's Regeneration trait. A severed leg is unable to attack and has a speed of 5 feet. A severed arm has a speed of 5 feet and can make one claw attack on its turn, If its head is severed, the troll loses its bite attack, with disadvantage on the attack roll unless the plague construct can see the arm and its target. If both its arms are severed, the plague construct loses its claw attack. If its head is severed, the plague construct loses its bite attack and its body is blinded unless the head can see it. The severed head has a speed of 0 feet. It can make a bite attack but only against a target in its space. The plague construct's speed is halved if it's missing a leg. If it loses both legs, it falls prone. If it has both arms, it can crawl. With only one arm, it can still crawl, but its speed is halved. With no arms or legs, its speed is 0, and it can't benefit from bonuses to speed.

Actions:
Multiattack. A plague construct gets two attacks, one claw attacks and one bite attack
Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 5 (1d4 + 3) piercing damage.

Hmm... you want a CR, right? Let's see...

Equivalent HP = (38+30+14)x3 = 246
Equivalent AC = 10
Defensive CR: 9

DPR = (11+11+11+14)/3 = 15.67
To-hit = +5
Offensive CR: 3

Final CR = (9+3)/2 = 6
...Wow. CR 6 with 38 HP. That's... dicey. I'm going to echo the DMG here and say this thing shouldn't have all those damage immunities or regeneration. It should just have more hit points. And even then, is a big sack o' damage absorption with one (one!) attack routine any fun to play against? It sounds like a dreary, soul-crushing slog.

Player: "Oh, I know what'll get us past these things so we can start having fun again: I'll Polymorph them into rabbits!"
DM: *trollface*

Agreed. Killing this thing is either going to be an absolute nightmare or a total walk in the park depending on party class composition. A 5th level Devotion Paladin facerolls one of these a round, a Lore Bard sits and waits for the fight to be over.

Aside from what else is said nothing about it screams plague. Where are the diseases or even poison like effects of this creature?
