Managed Spawners are the spawners used on Skyblock islands. A spawner is a stack of units of one mob type. It does not release mobs into the world: each unit produces mobs into a tank at a fixed rate, even while you are offline, and you harvest the tank by hitting the spawner's display mob or by letting a collector or a mob robot do it for you.
How the system works#
- Buy a spawner item in
/shopunder Spawners (see Obtaining Spawners). The mob must be unlocked by your island's Mob Mastery. - Place it on your island. Each new unit of a mob costs a little more than the previous one on the same island (the expansion fee); see Placing and Stacking Spawners. Placing again next to an existing spawner of the same mob merges the units into one stack.
- Wait. Every unit adds 240 mobs per hour to the tank at level I. The tank holds 8 hours of output and stops growing when full (Spawner Production).
- Harvest. Hit or shoot the display mob above the spawner to reap mobs and roll their drops, up to your reap capacity per hit (Reaping Spawners). Collectors and robots in range harvest at a reduced share of the drops (Automation yield).
- Upgrade. Spend money per unit on Level (production multiplier up to x3.0), Tank (up to 48 hours) and Automation yield (up to 85%); see Spawner Upgrades.
Right-click the spawner block to open its menu: mob, units, level, production per hour, tank fill, upgrades, storage and the expansion fee for the next unit. The block shows a hologram with the mob, units and tank fill, for example Tank: 120/1,920.
Mobs#
All 17 mobs are bought for money. Nether mobs work only in the island's Nether, End mobs only in its End (Spawner Restrictions), so those dimensions must be unlocked first (Island Dimensions (Nether and End)).
