For The King

The Armory is a hex area that becomes available after progressing in the second continent during the Frost Adventure campaign. The game is randomized so the exact location may move around but the game calls its location out when you’re far enough along. Land in it, which creates two more objectives - then find and complete two “ice shrine” dungeons located on small islands in the “frigid sea” area. Each shrine is a dungeon (level 6 for me) with seven encounters (not all are battles, and the last room is a treasure box with a key for the armory). Return to the Armory with both keys and claim the great treasures inside and cheevo will pop.
