Giovanni's Workshop Boosts!
Go to the woodshop to make 2 ladders and you will be prompted to use a workshop boost.
This explains how the boosts work...
All you have to do is click on the small green question mark at the bottom of the workshop screen to choose and activate a boost for that workshop. The Woodshop boost is to double the production of items made there. This boost will last for 5 minutes only, so get to crafting fast.
To get more boosts visit Giovanni's Contraption located in the Southern region of Cinder Caldera.
