Help with an item

[Iconik]

This is a shot in the dark but the community here never ceases to amaze me. I was looking through either Adventure Vault 1 or 2 and came across an item (I cannot remember whether it was wondrous item, armor, weapon etc) that had the word "acorn" in the description.

Again, I'm asking a lot here. I NEED the name of that item so I can put it in my game. Thanks in advance if you know what item I'm talking about.

I knew I could count on you guys. Amazing.

Sadly, I thought I read that it was a lvl 4 or 5. Guess I won't be using it.

You could use Phantom Soldier instead:
Phantom Soldier

This tiny figurine is carved in the shape of a warrior and can be used summon a life-sized illusion of the depicted warrior to distract your enemies in battle.
