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. It only picks up things it can sell, so anything without a price stays on the ground.
• 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 $10,000,000, $40,000,000, $75,000,000 and $125,000,000.

• Sweep is how many items it picks up at once. Every Collector checks twice a second and takes 2,500, 12,500, 25,000, 50,000 or 125,000 items per check, so a top tier Collector handles up to 250,000 items a second. On a stacked mob farm dropping thousands of items at once, this is the upgrade that stops things despawning.
• Multi sets the price auto-sold items fetch: 0.5x the shop price at tier 1, then 0.6x, 0.7x, 0.8x, and 0.9x at tier 5. A fully upgraded Collector earns 1.8 times what a new one does.
• Space is storage, from 100 to 10,000 stacks. 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, at the Multi rate above. Turn it off and you can sell the stored items yourself at the full shop price.

Where to spend first: Sweep 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.
