We did a few duels with Mir. I was quite pleased with Throwbarb, however it has a drawback: the Javelins run out very quickly. About 4 sets of Javelins would be needed to duel comfortably, without worrying about running out of ammo (speaking about comfort switching Javelins mid duel, but you get the idea). And they all need to fit in the inventory, which puts a serious dent into life total. The build is fun and enjoyable still.
