In yet another brand new Lost Ark Korean open beta gameplay video, YouTuber "end1e" shows off the Devil Hunter in action in a story scenario at level 33. "The Devil Hunter is one hell of a gun-slinger. He makes use of three different stances."
From the Lost Ark Gamepedia site:
If you can think on your feet and have cat-like reflexes, the Devil Hunter will be your best choice.
- The first Stance is quick on the draw with Double Handguns. This is best for eliminating fast approaching enemies.
- For larger, closer enemies, nothing works quite as well as the Shotgun Stance.
- Lastly, the Rifle Stance is used to snipe off enemies in the distance that are better to not deal with in closer range.
