Another items that you can take from the chest are:
Dream Blossom Staff
Batwing Hat
Those are the items that I got from the chest, apart of those that you already mentioned. I also heard a rumour about Wand of Dimensions, but I personally never got it nor do I know anyone who did. I was taking items from this chest for 3 months straight and never got anything better that the mentioned items. Neither did any of my friends. I hope I could help you.
Wand of Dimensions is a very rare loot from the boss Mazzinor in Secret Library Quest.
