Zombie Witness

Zombie Witness is a hardcore escort challenge. One nametagged zombie, your Witness, is bound to you. If it dies, you die.

• The Witness is a normal zombie that hunts you, but it can’t pick up items or wear gear.
• It must stay within 32 blocks of you. If it doesn’t, you take half a heart of damage every second.
• Your max health is the Witness’s health. Your hearts bar shrinks with it, in half-heart steps.
• You regenerate normally up to that cap. The only way to raise it is a Harming splash potion on the Witness.
• Portals: lure the Witness through first, then follow. Being in different dimensions counts as too far.
• New worlds start at midnight.

Requires Fabric API. Install on the client for the hearts display.
