Spawners on ToastCraft can be mined using a pickaxe enchanted with Silk Touch. This allows them to be used more easily in player farms.
Some spawner types not normally available in vanilla can be obtained using spawn eggs. Right-clicking a mob spawner with an egg changes the spawner's mob type to that of the egg.
Any type of spawn egg can be used to convert a spawner, but not all mobs drop eggs. Vindicator, Evoker, and Ghast spawners were once available but have since been removed. Iron Golem spawners can no longer be created but still exist on the server, making them valuable artifacts.
Sneak-right clicking on a spawner will convert XP levels into Bottles o'Enchanting.
