Obtaining new cards and leveling up your army are the most important steps to strengthening your army in Wild Beyond. Aside from PvP bonus chests and the daily Deals in the Store, the Expand Your Army and Recruiting Expedition quests will help you the most in getting the best units for victory in battle.
Expand Your Army
These quests unlock the ability to find new units in your PvP bonus chests. For example, Ice Acolytes are locked early on in the game (it shows up as a silhouette or "shadow" in your upgrade lab). Once you complete the Expand Your Army quest that unlocks Ice Acolytes, with a little luck, they will start to show up in your PvP bonus chests. Please note that unlocking a unit in these quests does not automatically grant you a copy of them. It simply allows to to start finding them in chests.
Unlike the Expand Your Army quests which allow you to start finding units in your PvP bonus chests, the Recruiting Expedition quests give you actual units cards! Once you complete all the requirements for one of these quests, you'll be able to choose from three randomly-generated cards or Alliance Tokens. If you're lucky, you might even see a Legendary Unit!
