Logistics Guild

The Logistics Guild is how you unlock the better Upgradeable Hoppers. Anyone can buy a Link Hopper. The Fast Hopper and the Collection Hopper need a guild license, and you earn each license by actually running a hopper network.

Find the quests in /quests > Harbor Academy. They unlock one after another.

Getting started: A Current of Items

This Harbor Academy lesson opens once you finish the rank-up step of First Day at Sea.

Browse Special Utilities in /shop.
Place one Upgradeable Hopper.
Link it to one container.

Reward: $5,000. A Link Hopper ($150,000) is the one to buy, since it needs no license.

Tips

“Collected by suction” means items your hoppers pick up off the ground. Items you insert by hand do not count. Park a hopper under a farm or mob drop and let it work.
Every upgrade goal can be done on a single hopper, so you never need to buy a second one just for a quest.
The licenses are permanent. Hoppers you already placed keep working no matter what.
Licenses unlock the item in the shop; you still pay the shop price and follow its daily limit.
