The Stash size has been increased and gambling got a higher chance of getting uniques and sets. And many more changes. The goal for this mod was to enable all the Diablo-content for the single player while keeping the 'vanilla-feeling'. This mod emphasizes on the distinction between Drop-Mods such as 'The Perfect Drop Mod'.
It is not the goal of this mod to rain-down uniques on a player. It rather wants to give a player the opportunity, or better, the possibility of exploring the full content of the game without losing its core mechanics. So if you want to play a single player session and want a realistic chance of actually getting unique items like Tyrael's, Windforce or Grandfather, then this mod is for you. It is of course not guarenteed that you will find all of the items the game has to offer, but it is certain when played multiple times! This mod is also fully functional with TCP/IP local multiplayer and works with the newest version of the game (1.14d).
