Fight Dungeon Bosses each day to earn Jewels to craft Mythic Troops, Weapons and other items in the Soulforge.
To unlock the Dungeon you must complete the Quest Line in Drifting Sands. Once the Dungeon is unlocked you can find it in the Games Menu on the World Map.
Inside the Dungeon are the 2 Mini-Bosses and the Mega-Boss. These 3 Bosses look like the troops in your collection but they're much more powerful and have special power ups that normal troops don't have. You can see what special abilities the Bosses have by selecting the blue ? icon on each boss.
For example in the Arcane Dungeon, King Bone Dragon not only destroys 25 Armor and creates 9 Skulls boosted by Armor removed like a normal Bone Dragon, he strips ALL Armor and creates even more Skulls each time he casts his spell.
When you defeat each Boss you're rewarded with Jewels, Shards and Diamonds which you can use to craft Mythic troops and other items in the Soulforge. Be sure to save these up for something you really want!
In addition to the Rewards given for defeating each Dungeon Boss, once you've defeated the first Mini-Boss you are able to purchase the Daily Gem Bounty from the Dungeon Offers menu found in the top right corner of the Dungeon. It costs 50 Gems and provides you with even more Jewels for the Soulforge.
The Daily Deal is also available as an in app purchase if you want even more Jewels.
Note: Diamonds are NOT Gems. Gems are an in game currency which you can use in the game shops. Diamonds are resources used for crafting in the Soulforge.
Different Dungeon every day
There is a different Dungeon with different Bosses, Rewards and Offers every day. The Dungeon changes at Daily Reset every day. The schedule in GMT is as follows:
