Expedition squad

Players can alternatively gain Save The World Materials by using their Heros to take part in expeditions. There are three categories of expeditions: Land, Sea, and Air expeditions.

Expedition Slots
Expedition Slots can be unlocked by completing parts of the Main Quests.

Expedition Boosts
By selecting heroes with the matching hero class bonus, boosts will be granted. Depending on the type of Hero rarity used, the boost can be heavily impacted.

Completion
Expeditions automatically complete after the countdown. Expeditions can be completed/failed depending on the percentage of the slotted heroes. The tougher the expedition, the more boost is needed and the better reward will be granted.
