Zombie (5e Subrace)
From D&D Wiki
Ever wanted to be a zombie? What about an elf zombie? Or a dwarf zombie? Now you can! Just throw this subrace on to any race you want to play as.
Ability Score Increase. Your Constitution score increases by 1 and your Intelligence score decreases by 1.
Undead. Your creature type is now also considered to be undead, in addition to what it was before.
Unliving. You do not need to breathe, or eat food and water. Instead of sleep, you enter a deep trance for 4 hours, which confers the same benefits. You are immune to poison damage and the poisoned condition.
Zombie Slowness. All movement speeds you have are reduced by 10 feet, to a minimum of 10 feet.
Zombie Undeath. When you are reduced to 0 hit points but not killed outright, you can drop to 1 hit point instead. You can’t use this feature again until you finish a long rest.
Zombie Slam. Your heavy limbs can be used to deliver a powerful slam, which you can use to make unarmed strikes. If you hit with it, you deal bludgeoning damage equal to 1d6 + your Strength modifier.
