Spelunking Expeditions MASTERY!

Spelunking Expeditions MASTERY! is an event in Cookie Run: OvenBreak. It began on October 14th, 2020 to coincide with the release of Goblin Cookie. It provides additional rewards for completing Spelunking Expeditions. Each specific Spelunking Expedition provides a small reward, such as Coins, Crystals, Rescue Tickets, or Green Sugar Crystals, as well as a special Event currency, Ore. Each 20 Ore collected provides another reward, up to a maximum of 100, in a manner identical to Make It Shine! and other previous events.

Missions
Each mission is only completable once, except for the daily mission "Succeed at any Spelunking Expedition". Every Stage of Spelunking Expeditions has an associated mission. If a Stage was completed before the Event was added, it does not count and must be completed again. Harder Stages provide more Ore, but do not provide more Crystals, Coins, Tickets, or Green Sugar Crystals. Some Crazy difficulty stages give a Rainbow Cube reward.
