First time I faced them in duel mode. Currently Hunter lvl 33. Those bastards are sick making working hard on my evade. They love moving a lot making life as hunter harder so I had to use gunslash to keep them at bay. I ran out of mates for the first time in the game in boss battle I had to play surviving mode. Eventually, I died and realized my armor is weak. I guess I will need help to defeat those speedy bastards.
