Legend of Keepers: Feed the Troll

Out of all the DLCs, this master is the most aggressive in terms of damage and the way you gain power. Thanks to blessings your monsters gain more damage to specific type of attacks, to the point they can almost one-shot heroes. Then you get access to various spells, similar to Enchantress which you can improve those with blood. This can lead to a hilarious strategy of purchasing monsters just to sacrifice them for more blood at the altar. If any of this sounds interesting to you, then don't hesitate trying out Shaman.
