Im working on a MLD barb.

What is better 2x Oath (highlandblade)
or oath (highland blade) + hustle (legend sword)

Or maby rare weapons?

really depends on what you dueling and what frames your looking to hit. I personally like a rare with fools mods and a oath just for the simple fact oath is a great cheap wep and the bone spirit it casts is really underrated but best combo would be a fools/cruel

its best to pair Hustle with Flow.
