So many to choose from! I was having trouble between Gogh Reed, the Nightmare, and Inari's Beads... but, anyways, you'll see my answer on the facebook thing!
I don't have a favorite EI since I like them all (with a few exceptions). However...wouldn't have Gaia thought that we would already own our favorite EI? If it is our favorite EI, we most likely would have bought it already right? I guess you can always use two I guess... I wish this was, which EI would you like to own...
If it was that I'd chose Picolitrosso's Urn however I don't possess any item to match it, same with Hidden Ace which is also very pretty. The only EI I would actually like to have and have use for if Noel's gift since I have an dream avi that uses it...
