Vanilla Spawners Expanded

A calibrated spawner is made with a Spawner Calibrator, after which its mob type, lighting, upgrades and other settings can be customized. Calibrated spawners can be mined and collected without Silk Touch. A mob blacklist and a mob whitelist control which creatures a calibrated spawner can produce, and an empty whitelist allows every mob except those on the blacklist.

Souls are taken from mobs with a Cursed Bottle, and the bottle can be reused. A captured soul placed in a calibrated spawner defines the creatures it generates. Four upgrades are available: Speed shortens the time between spawn cycles, Range widens the area where spawning works, Crowd lets the spawner work even when several mobs are already present, and Redstone lets a redstone signal control it. The mod has a detailed configuration file. Fabric API is required, and Jade is an optional companion. Installation covers the server and each player's game. Its license is the Creative Commons Attribution Non Commercial 4.0 license, and it is not open source.
