Weeping Zombie

Undead Fortitude. If damage reduces the weeping zombie to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.

Weeping Pox. A humanoid that comes within 5 feet of the weeping zombie must succeed on a DC 15 Constitution saving throw or contract Weeping Pox. If a humanoid succeeds on the saving throw, it's immune to the disease for 24 hours. A humanoid infected with the disease must repeat the saving throw every 24 hours, increasing its exhaustion level by one on a failure. This exhaustion can't be reduced until the disease is cured with magic.

Until the first level of exhaustion sets in, however, the humanoid has sharpened senses. Whenever this humanoid makes an ability check or saving throw against anything other than the disease, they can roll a d4 and add the number rolled. A slight fever and overexcitement are the only signs this condition comes from Weeping Pox

Slam. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 6 (2d4 + 1) bludgeoning damage and Weeping Pox.
