Treasure Cove is a special deal based 7 day event, offering paid rewards. To access this event, please click on the “Deal” and then select the “Treasure Cove” tab. There are 5 packs available for each day. These packs are linked via pipes, one for each of the five packs. Purchasing a pack unlocks the matching part of the map for the day. Once you’ve purchased all five packs, all five parts of the map will open, revealing the Grand Prize. All the packs are available for $5 each. The total cost for purchasing all five packs in the Vault of Enigma is $25. Daily packs and grand prize contents may vary based on server timeline. You can buy all the packs on day 5 and after, but every day before that, the packs regarding that day open up.
