Lethal – Legendary Survival Overhaul Addon

by HER0XP

Lethal adds an addon to Legendary Survival Overhaul that makes head and chest damage lethal, with reach set to 0.

ForgeNeoForgeServer-side onlyAll rights reserved1.20.1 – 1.21.1

What it does

Once installed, damage to the head or chest ends a player's life at 0 health, no matter how many hearts remain. The mod changes Legendary Survival Overhaul, which it requires, so the body-part rules come from that base mod. It is server-side only, so players join without installing it, and it is published for Forge and NeoForge for 1.20.1 and 1.21.1 under All rights reserved, not as open source.

Key features

  1. Instant head and chest death

    Hits to the head or chest drop a player to 0 health and end the life at once, regardless of remaining hearts.

  2. Body-part tying

    Vital body parts are tied to life, so damage that lands on them becomes a critical event instead of a slow loss.

  3. Configurable behavior

    The addon needs a configuration pass, letting the server owner set how the lethal rules apply.

Questions

Does Lethal need Legendary Survival Overhaul?

Yes. Legendary Survival Overhaul is the required dependency, and Lethal works on top of it.

Does a player need Lethal installed to join a server?

No. It runs on the server alone, so players need nothing extra to join.
