How to Unlock Minis in Warcraft Rumble
There are several ways to unlock characters in Warcraft Rumble. Unlocking Minis is important to upgrade your collection level for more experience. To do so, you can unlock Minis and Leaders from the G.R.I.D, by progressing through the campaign, or by purchasing them in packs.
The Mini Store is a 3x3 grid of rotating rows and columns. On it, there are Minis and other purchasable items you can buy with Gold. The shop cycles every day at 12 am, but it can also change up the row and column of an item when you purchase it.
If you don't want to wait, you can use Big Red Buttons to recycle the entire grid immediately. The store also has another type of cycle regarding the Leaders. Each week, the shop will feature a specific family of Leaders that will be available. This means that if the Grid is in the Alliance Event, you will only see Alliance Leaders.
The Warcraft Rumble campaign consists of missions you play to progress through the game and earn Sigils. As you collect more Sigils, you'll be able to unlock new Minis and Leaders. After reaching enough Siglis, you also be able to unlock the Heroic campaign to earn even more rewards.
