Useful Allays
by 0nicalls
Useful Allays turns allays into helpers that pass beneficial status effects to players standing nearby, based on the item an allay is holding.
What it does
An allay holding one of the listed items grants a matching effect to every player within a 14-block radius. The effects covered are Jump Boost, Slow Falling, Night Vision, Water Breathing and Fire Resistance, among others. Each item corresponds to one effect, so the choice of item decides what nearby players receive.
The behavior is driven by a datapack that checks allays holding items every 3 seconds and applies the effects accordingly. The mod is designed for servers: the server is required, while clients can optionally run it. Builds are published for Fabric, Forge, NeoForge and Quilt, covering game versions 1.21 – 1.21.11, and the source code is available under the MIT License, which makes the project open source.
Key features
Item-based effects
Each supported item held by an allay grants its own effect, such as Rabbit Foot for Jump Boost or Golden Carrot for Night Vision.
Area of effect
Players within a 14-block radius of the allay receive the effect, so a group standing close together benefits at once.
Periodic checks
A datapack re-checks the items held by allays every 3 seconds and updates the applied effects to match.
Combat and utility items
Ghast Tears, Phantom Membrane, Blaze Powder, Magma Cream and Golden Carrot are among the items that map to effects.

Use cases
Keeping a base supplied
An allay stationed near a base can hand out Water Breathing or Fire Resistance to nearby players without a potion in hand.
Exploration on a server
Players travelling through caves or the Nether can receive Night Vision or Slow Falling from an allay that moves with them.
Who it’s for: Server owners who want allays to provide status effects to nearby players, and players who keep allays on a shared server.

What the author says
Enhances Allays by allowing them to provide beneficial effects to nearby players based on the items they are holding. It's like a level 1 beacon with wings! The datapack checks every 3 seconds for Allays holding these items and applies the effects accordingly.
