There is a new campaign called “Discover Smaug”.
It is the shortest campaign from The Hobbit Kingdoms, players don’t need to farm any keys.
The campaign has just two maps and you need just one key to unlock the second map.
The might range of the enemy outposts are from 36.000 to 48.000 on the first map and 144.000 to 720.000 on the second map. You lose like 10.000 tier 3 troops on the last outpost from the campaign (fighting Smaug, the dragon), without any buffs.
Rewards? Some 1 hour speedups. Fighting Smaug, the last outpost, you have a chance to win “Smaug’s Loot” (Erebor Treasure Chest). My chest had a Hero’s Renown (+1 level for a hero that is over level 212).
