New skill trees with 210 new skills, new base items, gems, runes, uniques, runewords, sets, crafting improved monster AI and new monster types, elite and heroic monsters, 28 uberquests for advanced characters, 5 challenges. Compatible with Diablo II Lord of Destruction 1.10/1.11/1.12/1.13 (PC/Mac).
It is a awesome mod, a complete change from my normal gameplay over the classes.
A few bad things such as lack of good decent loot when killing so many enemies and dying trying to get them, and the overpowered Countess on the 1st act.
But besides that, it is one of my fave mods.
