Today I was in a Vana run with some of my friends, on D26 we got to some prize boxes after completing the path on the right. One of the boxes dropped a Volcanic Plate Helm for me. I told my other friends about it and they told me to post it here. I just wanted to let you all know that it still is possible.

This may sound like nitpicking, but they're called treasure boxes. Prize boxes are something else. For example, you get prize boxes from the Forge occasionally.
We have a long-running thread for documenting item drops from treasure boxes:

So please post your find there, not here.
