Bloody Executioner

A large improvement over the Blade Masters, these executioners have gained an immunity to Sickness, and while they lost the Single Sweep skill from their predecessors, they instead have gained couple of new ones: Flame Wave, which hits all party members twice for Fire-elemental damage; and Hell Crusher, which hits a party member three times. Therefore, blocking their attacks isn't as straightforward as it was for previous monsters of the type, so it's advisable to be on guard in order to avoid receiving too much damage.
