This mod has the purpose of raising challenge to the maximum, giving more variety (monster types, items, spells, bosses, unique items), providing more randomness (monster generation on levels, monster stats, varying mob sizes and bosses, AC on items, level colouring, drops, uniques with greatly varying stats, etc.) and making the multiplayer experience fully functional. And, most importantly, this mod has one main goal: to give maximum pleasure from playing the game.
