Warning: This guide contains major spoilers for all of the new content in BG2:EE; much more so than the guide for BG:EE. It is my strong recommendation that anyone with the slightest bit of interest in the new storylines should play through the game at least once before reading any further.
There is now a spoiler free version of this guide in the post below this one
This is a list of all the new notable magic items in BG2:EE.
I am not including underwhelming vanilla items of which there are many.
A list of items in BG:EE can be found here:
