Pillager Assault Brigade - Priestess's Revenge

Illager legions are summoned in response to a curse, and the sky dims to a blood-red hue while a heavy, unnatural heartbeat sounds in the player's ears. Threats sound across the whole server, and murderous assassins come out of the shadows, growing in number and strength over time. The priestess's hints about how to stop her appear in a crumpled paper note that a newcomer receives.

The mod adds items tied to the storyline. A potent elixir dropped by the Avengers grants burst strength and leaping power, a Valkyrie Weave item is crafted with an existing elytra by combining several pieces on the crafting grid, and Steel Wings are an enchanted elytra whose wings resist fraying and offer the same protection as a chestplate. Players earn the Valkyrie title through the adventure, and the curses come from a forgotten temple.

The mod is published for Forge only, across 5 release versions, 1.20.1 – 1.20.6. A server running it needs every connecting player to have it too. It is released under the MIT License, and the code is not open source.
