What creatures display another creatures item on them?

Question

For example, an Infernalist is shown wearing what appears to be a red coloredFerumbras Hat which is dropped by Ferumbras and Ferumbras Mortal Shell

.... What are other examples of creatures displaying what appears to be another creatures item on them?

Maybe I provided a bad example, as it's not really a Ferumbras Hat because a Ferumbras Hat is dark and on the Infernalist it's clearly red but it's such a similar sprite it reminds me of his hat! Is there any other examples like this?

Answer 1

To be honest the only thing which comes to my mind is Gear Wheels   that wears War Golems, Damaged Worker Golems , but it is dropped by other kind of mago-mechanics creatures like Worker Golems, Control Towers, Iron/Golden and Diamond Servants and it's replicas and more.

Of course there is a lot of examples when monster wears an item that can be dropped by other monster, but this item is also avaliable in his own loot.
