Spatial Harvesters [FABRIC] Mod 1.16.4–1.19.2

If you want it to use a specific weapon, hold the key in your main-hand, said weapon in your off-hand, and break a block while sneaking.

It doesn't support specific configuration or bosses but will farm just about any entity in the game that extends the MobEntity class, isn't a boss, and isn't blacklisted in the config.
