Touhou Little Maid: Beacon

Holding a beacon and right-clicking a maid equips it in her helmet slot. The beacon block is then rendered above her head, and the rendering can be turned off in the configuration. A maid carries a beacon level that starts at 0, and the level is raised by upgrading her with iron, gold and diamond blocks at levels 1, 2 and 3. Higher levels allow more effect auras and a larger total Cost.

Each aura is a beacon-like effect that the maid applies to players and other entities nearby. The player chooses which aura to enable or disable. Activating an aura consumes a fixed amount of Cost tied to that aura, and the total available Cost depends on the maid's current beacon level, which limits how many auras can be active at once. The Ender Dragon is among the entity types the auras can affect, and the configuration file controls the rules, costs and entity types.

The mod requires Touhou Little Maid, and it runs on client and server, so the server and every player need it. Files are published for Forge and NeoForge, for 1.20.1 and 1.21.1, under the BSD 3-Clause License, and the source code is public.
