Energy is a special resource required for participating in expeditions. You can use it to clear the map of objects (stones, trees, bushes, grass, etc.), complete tasks and advance the search for quest items.
Energy isn't infinite — it builds up. A full energy bar has 200 units of energy. Energy regenerates at a rate of 1 unit per 30 seconds.
The amount of energy required for regular and temporary expeditions and Olympics is the same. Energy can also be purchased for Gems during an event, collected from temporary energy generators (special location decor), received as a reward for completing events, prepared during a temporary or regular expedition at the location's bonfire, and obtained as a bonus from special chests, wooden boxes, and barrels.
