A cursed version of totem of undying that turns you into an undead when you die with it

Cons:

• Burn with sunlight (Wearing a helmet negates this at the price of damage to the helmet)
• Sink on water
• Healing harms you
• Villagers run away from you
• Unsatiable hunger
• Can only eat raw meat
• No saturation
• Wolves and Iron Golems hate you (Bonus damage to you)
• Smite deals bonus damage to you
• Reduced xp gain

Pros:

• Undead mobs are Neutral (Including the Wither)
• Harm heals you
• Immunity to poison
• No need to breathe
• Immunity to wither
• 2 armor points (Zombies have them too, so why not)
• Killing Villagers turns them into allied zombie villagers (?)

Obviously only obtainable by the cursed one, might be undone by applying weakness and eating a golden apple (?)

This is a big suggestion that I do not like as it stands, to be honest. I might adapt some parts of it as various items or mechanics in future, but so far I have a lot of other stuff coming right up, so...
