Tunnels & Trolls Sewers Of Oblivion Solo 13

This solitaire takes place beneath the City of Terrors, but is not directly connected with that solitaire adventure. Sewers of Oblivion is not for novice adventurers - instead characters up to 7th level, with as many as 425 combat adds, will find a challenge or two within. However, less mighty characters (150-300 combat adds) will find a more exciting adventure and greater rewards in the end."
