Runner Zombie (5e Creature)
From D&D Wiki
Medium undead, chaotic evil
Saving Throws Con +4
Undead Fortitude. If damage reduces the zombie to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is from a critical hit. On a success, the zombie drops to 1 hit point instead.
Keen Hearing and Smell. The zombie has advantage on Wisdom (Perception) checks that rely on hearing or smell. In addition, if a creature is below its hit point maximum, and its blood has been shed in the past 5 hours, the zombie can track the creature and has a bonus to any ability check it makes to find the creature (+1 within 10 miles, +2 within 5 miles, +3 within 2 miles, and +4 within 1 mile).
Pounce. If the zombie moves at least 20 feet straight toward a creature and then hits it with a slam attack on the same turn, that target must succeed on a DC 12 Strength saving throw or be knocked prone. If the target is prone, the zombie can make one bite attack against it as a bonus action.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage. If the target is a human, it must succeed on a DC 16 Constitution saving throw or contract the zombie virus and gain a level of exhaustion. Every hour the infected creature must succeed on a DC 17 Constitution saving throw or take 11 (2d10) necrotic damage and gain one level of exhaustion. After 6 failed saves, the creature dies and rises as a zombie.
Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage.
Feeding Frenzy. When a creature is reduced to 0 hit points, the zombie can move up to 20 feet directly towards it and make a bite attack against it.
Slowly shambling, brain eating and unstoppable, these monsters have been glorified by pop culture, and other sources. This stat-block is a representation of your average zombie, cold, dead, and hungry. It spreads its unnatural plague by biting victims, and is very good at hearing and smelling blood and fear.
