Helms

Hmm.. If you have some treasure chest, the The Shadow of Death Mask helm looks pretty good with Legion Titan.

Others:
Undead Legion Crown
Undead Legion Face

That's all i know to fit best with Legion Titan and Caladbolg.

Undead Legacy Helm is an option.

Oh. I figured you'd have it. It went rare just a few months ago... Any cc helm should do.

Undead Legacy Helm is a former staff item... Most people no longer have it because they didn't bother reading the DN's/tweets about the helm going rare as soon as the war ended, so they deleted the helm and never grabbed it before it went rare.

I would just scan the helms list on the wiki. Just open a bunch of them in tabs and close the page if you don't like the helm.

Have you tried what i suggested to you?
