Kingdom Hearts II Organization XIII Mushroom Items

I've been on a quest to find all the synth items to get the last Orichalcum+ from the Moogle vendor to finally make the Ultima Weapon. However, I am missing one synth item -- it's one of the ones you get from an Organization XIII Mushroom.

I have 3/4, the three I have, have these descriptions (I can't read Japanese, so I'll describe how they look):

1. Ends with a Japanese character that looks like an English "S"
2. Ends with a Japanese character that looks like a "<" sign.
3. Name ends with a Japanse character that looks like a "6."

So I'm missing the one that is not listed above. Can someone please tell me which Organization XIII Mushroom drops the last item, or what I need to do to make an Organization XIII Mushroom drop it (I'm on Critical Mode, have both Lucky Luckies on Sora, have Lucky Lucky equipped on Donald and Goofy as well).

Thanks!

 

Sorry to tell you, but the Organization Mushrooms all drop the same items.

If you do exceptionally well on them, they will drop one of all 4 items (i.e. the shard, the stone, the gem and the crystal).

Pick the Mushroom you do very well against, and they should drop all 4 each and every time.

 

Hey, thanks for the reply, a friend of mine and I were working on getting this item tirelessly, and while I was posting this thread, he managed to get under 10 seconds on that mushroom in Agrabah (that self-healing one), which is supposed to be really good and he got the last item (I think that's the Crystal), so we were all set and finally got the Ultima Weapon :).

Thanks!
