Bravura may derive from the origin of the word rather than the "definition" given.
- http://www.merriam-webster.com/dictionary/bravura -
"Italian, literally, bravery, from bravare to show off — more at bravado"
So it's possible that the Axe is named for the sense of "Bravery" of fighting off against monster without a shield and tanking at the same time lol.
