Dungeon Master (by ASA)

Klein is a young paladin of the Blind Lord, a thirty-second level adventurer. Together with his band of adventurers, this young man wishes to destroy the monsters that threaten the civilians, to become stronger, to level up, to gain fame and honor! But will he succeed, if danger can lurk around any corner, and death and life in this world is determined only by the value that fell on a twenty-sided die, which throws the blind god of luck? Especially when they accidentally crossed the path of a powerful Lich trying to become a god.
