Friendly Phantoms

Friendly Phantoms is a small mod that adds a gamerule that stops phantoms from attacking.
It doesn't stop them from spawning, letting you still farm them for that good ol' phantom membrane.

The phantoms attacking is off by default.
You can use the command /gamerule doPhantomsAttack [ true | false ] to change the behaviour per world.
Or simply set the gamerule in the gamerules menu on world creation.

The mod is completely server-sided but can be installed on the client for single player worlds.

Feel free to use this mod in modpacks hosted on Modrinth and/or CurseForge.
