I know they added weapon, like staff that Kagha gives you after "good ending" with the druids. It is important to note that they added not just a druid class, but also a quest branch that concerns druids.
That was the sort of thing that I was fishing for. It felt good to be award a new title and to get a new unique magic item.
I think there was some new armour added for killing the Bulette but I never managed it until my third play through so I cannot be sure.
I am sure there are many other things which I have forgotten / thought I had missed.
@DragonSnooz - Weighted Dice, least said soonest mended.
@CJMPinger - I am intrigued to see how smiting is handled.
