Spade

The spade is a tool that can be used to dig. Digging can uncover various small items, chosen at random. In Adventure mode, digging also uncovers several special items which advance the plot.

To dig, simply equip the shovel and press the right mouse button. You can be standing on rock, or even floating in the ocean—digging will still work.

The items you can dig up are determined by your Digging skill, which goes up by one point each time you dig.

What you can dig up

 * Regardless of your Digging skill, you have a chance to excavate stones, pebbles, and worms.
 * Once you reach the Shovel Amateur rank (50 points), you can also dig up insect parts and mushrooms.
 * At the Shovel Adept rank (100 points), you have a chance to dig up bitterroots.
