Vaulted End
Vaulted End is a server-side Fabric modification built on the Polymer framework that completely transforms the elytra acquisition system in the End dimension. The main goal of this enhancement is to optimize gameplay on multiplayer servers by providing newcomers with a reliable way to obtain elytras and shulker shells even in long-explored worlds, without the need to travel vast distances in search of untouched End ships.
Enhanced End Ships System
End ships are now equipped with vaults and trial spawners that replace the traditional elytra item frames. Each vessel's upper deck generates a shulker trial spawner that guaranteed drops an elytra vault key. In the lower section of the ship, players will discover two endermite spawners rewarding golden carrots, rockets, and shulker shells.
The elytra itself is now securely stored in a vault where the item frame used to be and requires a special key obtainable from the shulker spawner for access.
Ominous Treasure Hunts
Approximately one-third of all End ships generate an additional Ominous vault. Similar to trial chambers, with the Bad Omen effect active, players can challenge ominous spawners that drop Ominous elytra keys. However, exercise caution - confronting these enhanced spawners demands serious preparation and combat skills!

Server Configuration
The modification is fully compatible with vanilla clients thanks to Polymer technology. Players can enjoy all the benefits of the enhancement without needing to install it on their clients. For complete immersion, it's recommended to use the accompanying resource pack that adds unique textures for elytra vault keys.
Vanilla client users who prefer not to download the resource pack will see elytra keys as regular trial keys, and ominous elytra keys as ominous trial keys.
Licensing Terms
Early versions of the modification before 1.3 were distributed under the MIT license. Starting from version 1.3.1 inclusive, the project transitioned to the Apache 2.0 license.
