It takes 10 fuel for every attempt to increase the steam level. To do this, you’ll need to pump fuel into the Steamworks (we’ll get into acquiring fuel later). You’re tasked with keeping it fueled, so all of the new hunters can stay warm in the frozen tundra. The Steamworks is a big machine in your new town, Seliana. It’s also completely random and a little time-consuming, so it’s important to chip away at it between missions. The Steamworks is a bizarre mechanic, but it’s a great way to fill your stores with items. Shortly into Monster Hunter World: Iceborne, you’ll unlock the Steamworks in Seliana.
