Collectible. All player's trolls get 2 levels. If both parts of caves are in player formation, then all player's trolls get 4 levels and immunity to water (ico) champions.

The land of Flaming Waters is not only rich in history but its citizen variety. Diversity is a crucial part of the land. Here it is possible to meet Elves and orcs, wherebeasts and vampires. Deep in The Haunted Forest, trolls live here as well. Between Magnetic Sea and Sea of Life, Caves of Trolls are hidden from wandering eyes. This is their home, their roaming grounds, safety heaven, and battlegrounds. Yet, enemies rarely get to celebrate here, in Caves of Trolls. Such a well-hidden location isn't something you'd like to stumble upon by accident. And not even the best of warlocks and wizards can solve the riddle of trolls' immunity to water powers. One miracle follows the other in the caves, but the winning dice is mainly on the troll's side.
