All of the enemies are physical attackers with negative slash resistances and -60% resistance to Disable. Most of them are Light Slash types. After some enemies are defeated, 2 more Dark Dragoons will show up near the top left area of the map, and 2 Light Samurais past the brick walls.
The Paladins will start the fight by using Saintly Wall, and they can use Taunting Blade when they get in range. This can end up pulling your team towards them if you play full auto. The Dark Dragoons have Light Eater passives and will be attacking from the side, which can be an issue if you are using a Light element tank.
