Upgradeable Spawners

Upgrade your spawners by placing an item frame anywhere on a spawner and placing the upgrade item into that frame. The upgrade item then gets consumed, emptying the item frame. Available upgrades: - Eye of Ender: Entity spawn count (4 Upgrades. Up to 8 entities) - Heart of the Sea: Decrease maximum spawn delay (4 Upgrades. Down to 10 seconds) - Daylight Detector: Increase spawner activation range (4 Upgrades. Up to 80 blocks) - Echo Shard: Decrease spawn range for smaller farms (3 Upgrades. Down to 1 block) - Nether Star: Disable spawned entity AI (Single upgrade)

Disable the spawner by having a redstone torch placed inside an item frame that's on the spawner. Remove the redstone torch to resume the spawner.
