A Collector is a block that hoovers up everything that drops near it, stores far more than a chest ever could, and will sell it for you while you are away. Buy it with Coins in /coinshop.

If minions and spawners are how you produce, the Collector is how you keep what you produced. A farm without one is a farm quietly throwing items away every time a chest fills.

What it does

• Picks up dropped items around it automatically.
• Collects experience as well, within 8 blocks, so a mob farm is not wasting levels.
• Shows a floating display above itself with what it is holding.
• Can sell its contents for you, turning a farm into income with no chest to empty and no trip home.

The four upgrades

Each track upgrades separately, so you can put money where your farm actually needs it. Tiers cost $1,000,000, $4,000,000, $7,500,000 and $12,500,000.

• Speed is how often it sweeps, from every 2 seconds down to every quarter of a second at the top tier. On a stacked mob farm dropping thousands of items at once, this is the upgrade that stops things despawning.
• Multi multiplies what you get, from 1x up to 1.25x. A flat 25 percent more output from the same farm, forever.
• Space is storage, from 28 slots to 448. If you log off for a day, this is what decides whether the farm was running or standing still.
• Auto-Sell turns collected items into money without you touching them.

Where to spend first: Speed if your farm is big and things are vanishing, Space if you are away a lot, Multi once the other two are comfortable.

Limits

• You may place 10 collectors.
• One collector per chunk, so they cannot be crammed into one corner.
• Collectors keep working while you are offline, as long as the chunk stays loaded. That is what Chunk Anchors are for.
