Lead your party against the giants! Will you be brave enough to challenge the towering, unconquered Giant Fortress? Discover it with the new 0one's Blueprints: Giant Fortress.
The Giant Fortress stands on the very top of the highest mountain of the Glacial Spine. A path, haunted by snow trolls, hobgoblins and other dread monsters, leads to the fortress. A small plateau before the fortress houses the hobgoblins encampment. The hobgoblins act as servants and cannon fodder for the giants.
The fortress is a massive structure made of granite and grey stone dug from the very belly of the mountain. The building rises to the sky for 3 levels (although, being giant-sized, it is roughly 160 feet high).
