Worksites are used by minions to do that certain job for you.

Animal Farm

Allows you to set a limit of a certain type of animal that has to be left alive after a minion harvests any extra animals that are more than the set limit. You need to place a sword in this worksite for a minion to start working there. If you have sheep in the worksite, you can also add shears to make the minion shear them.

Crop Farm

If you place a hoe in this worksite, a minion will till the land and place your crops that you specify. If you put bonemeal in the worksite, it will use that on the crops.

Quarry

Work In Progress

Tree Farm

Like the crop farm, but you need to supply this worksite with an axe, and you can supply bonemeal to this one as well.

All of these worksites can be given a set radius.
