It was actually one of the Cinderlands Dynamic Mission Bosses...Samju I think his name was. The martial artist who keeps summoning minions to fight with him. I wanted to fight him to test myself even though I believe that it is not necessary to progress in the story.
I guess if you want to offer more help (which of course I am always grateful for), I will state the class my character is: Blade Master.
Thanks to both of you for your advice so far.
