Heavylytras

by therealfickle

Heavylytras changes how elytra behave when a player wears netherite armor, and only the server needs to run it.

FabricServer-side onlyAll rights reserved1.21.1 – 1.21.11

What it does

When a player wears netherite armor, Heavylytras disables elytra flight, which makes heavy gear a poor fit for gliding and combat. The mod affects items listed in the HEAVY ARMORS tag, and a datapack can modify that tag to change which items count.

Installation needs Fabric API. Heavylytras is server-side only, so players join without installing it. It is published for Fabric and covers 1.21.1 – 1.21.11, with 1.0+1.21.11-Diamond for 1.21.11 as the latest file in the beta channel. The mod is released under All rights reserved, and its source code is public.

Key features

  1. Elytra lockout with netherite

    Netherite armor disables elytra flight, discouraging players from gliding while in heavy gear during combat.

  2. Configurable item list

    The set of affected items comes from the HEAVY ARMORS tag, which a datapack can edit to add or remove items.

  3. Server-only install

    Only the server runs the mod, and clients join without installing anything.
