Can I take braggart's roar off of the battle hammer?

[Thomas Devlin]

I want to try braggart's roar on some claws, and I read that in only appears on the iron balls and as the default ash of war on the battle hammer. I know that taking it off of the iron balls is how you get the ash of war, but I don't really want to kill Bogart, so I'm curious if it would be possible to use a lost ash of war to duplicate it off of the battle hammer

[LuckyCheshire]

No, you can only duplicate the already-switchable AoWs. The lost ashes are kind of useless that way.
