Quenya Translation

Logan Pike #4728

Hi! I was wondering if someone may be able to help me. I'm trying to find a translation for "Hammers of Misfortune".

The best that I could do on my own was "Nambar Amarth/Umarth", or, Hammers of Ill-fate/Doom. It seemed to be the closest in meaning to what I was going for. Any and all help is much appreciated!

Nambar Umbarto "Hammers of Doom". Amarth is Sindarin.

Umbarto is also a name.
