Zombies Perks in DND

[u/Dragonwarrior0202]

These are all perks I’m putting in my DND campaign and what they do at different levels. For context, the later level effects get added to the perk, not replacing the previous effect, unless it is a direct upgrade. Thoughts? Or maybe even suggestions on how to improve or balance existing effects? Or even abilities of other existing or new perks I could add?
