Fuel

Fuel is a necessary material to be able to go on expeditions to different ember mines with your armada, this must be acquired before the expedition.

The cost of fuel will vary depending on the ember mine you wish to explore, the farther away the mine is, the more fuel will be needed by your armada to go explore it, the approximate value of fuel is 10% of the reward of that mine.

All fuel costs are calculated with the Ember Mine's base rewards, meaning, the fuel cost will not increase as you level up.
