Carrion Golem

Stench of Death. Carrion golems are foulness incarnate. Anyone who enters or starts their turn within 10 feet of it must make a DC 14 Constitution saving throw, unless the creature is a Construct or an Undead. On a failed save, the creature is poisoned until the start of its next turn. On a successful save, the creature is immune to the Stench of Death of all corpse flowers for 24 hours.

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

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

Disease. A carrion golem is befouled with a thousand festering plagues. Anyone struck by a carrion golem’s slam attack risks infection from a number of ailments. Roll 1d6 and consult the following to determine what particular sickness assails the victim. Each disease is permanent and the target may make a new save after each long rest. Diseases are cured by any effects that also cure poison.

1. Filth Fever. The target senses a raging fever coming on and starts weakening. The target must succeed on a DC 12 Constitution saving throw or become poisoned and has a 50% chance to gain a level of  exhaustion after a long rest. 
2. Typhoid Fever. The target's muscles cramp uncontrollably and is overcome with a bout of nausea. The target must succeed on a DC 15 Constitution saving throw or take 1d6 poison damage become poisoned.
3. Tetanus. The target's jaw muscles spasm and begin to stiffen. The target must succeed on a DC 14 Constitution saving throw or become poisoned. Each time the target attempts to speak, they must succeed on a DC 12 Strength saving throw.
4. Cholera. Lethargy washes over the target as painful cramps wrack their legs and stomach. The target must succeed on a DC 13 Constitution saving throw or become poisoned, can no longer take the dash action, and their speed is reduced by 10 feet.
5. Rupture Pox. Blisters suddenly form over the target's extremities. The target must succeed on a DC 14 Constitution saving throw or become poisoned. If the target fails the saving throw, whenever they make an attack roll or a saving throw, they must subtract 1d4 from the attack roll or save.
6. Scarlet Leprosy. The target feels their bones aching and weakening under the weight of their body. The target must succeed on a DC 20 Constitution saving throw or fall prone and permanently have one failed death saving throw until cured. This effect stacks.
