Mob spawners plugin has been added to the server (the plugin was made by myself, designed for this server).
You can now obtain mob spawners by either mining them from mineshafts and nether or by purchasing them from the spawn shop, below I'll be explaining shortly how they work.
Mob spawner type cannot be changed, mob spawner type gets automatically set to 1 random mob (the odds are stated below) when you mine it for the first time, and cannot be changed even if you place and mine it again.
Mob spawners are divided into 5 categories, depending on their rarity:
Super Legendary mob spawners (0.1% chance):
• Ender dragon
• Wither boss
