Spawners
Custom spawners are passive loot farms. They never spawn a live mob, you won't get swarmed. Instead the mob spins on display and the spawner quietly piles up its loot and XP over time for you to collect.

How they produce​
- Every 37.5 seconds, the spawner rolls its mob's real vanilla loot table and adds the drops (and XP) to its stash.
- Stacking multiplies the output, stack more spawners of the same type and each cycle rolls that many times more.
A spawner holds at most two double chests of loot and two double chests of XP bottles. Once it's full it stops accumulating until you collect it, so empty it regularly to keep it earning.
Collecting​
Right-click the spawner to open its menu. Three tabs (switch with the view selector):
- Collect loot — the accumulated items.
- Collect XP — stored XP handed out as Bottles o' Enchanting (7 XP each).
- Stack spawners — add more spawners of the same type to boost the multiplier.
In the loot and XP tabs you can Sell it all, Fill my inventory, or
Drop on the ground, with your live earnings shown as you go. Sell it all
pays the same as /sell: 50% of worth, minus the 5% fee.
Only one player at a time can collect from a spawner. If someone else is already in its loot or XP tab, you'll be told to try again soon.

Getting spawners​
- Buy from the shop in Shards (Shop). Tougher mobs cost more.
- Find them. A couple of types, Cave Spider and Silverfish, aren't sold and can only be found in the world.
- Adopt a natural spawner. Right-click a vanilla spawner whose mob is a supported type to convert it into a custom one (first time only). Sneak + right-click just places it as normal.
Available mobs​
Iron Golem, Cow, Pig, Zombie, Skeleton, Spider, Creeper, Blaze, Zombified Piglin, Enderman (all sold in the shop), plus Cave Spider and Silverfish (find-only).
Breaking a spawner​
You must use a Silk Touch pickaxe to break a spawner. Without it, the spawner won't break at all, and any uncollected loot/XP inside is lost. Collect first, then mine it.
A broken custom spawner drops back as an item (including any extras you stacked onto it). Silk Touch a natural spawner whose mob is a supported type and it drops as that custom spawner too, even if you never right-clicked to adopt it.
