Advanced Mob Spawner - Alec-WAM/CrystalMod GitHub Wiki

When given a Mob Essence it will spawn that mob just like a vanilla spawner. It also allows for a few upgrades.

Upgrades:

• Nether Star: No player needed to run the spawner.
• Pure Crystal Block: Doubles the spawning speed.
• Pure Crystal Ingot Block: Triples the spawning speed.
• Golden Apple: Ignores mob spawning requirements. (Ex. Light level)
