To get easy kills simply get the disarm strike and level it. Also level the single sword skill (small shield and sword)so you can use the skill. Now equip the disarm strike in a skill slot of your choosing and enter a battle royal. Hide behind a pole (or spining blades) and wait for them to get smart and go around it. Once they are infront of you attack with your wepon. And if they have a shield use disarm strike and aim at the shield. And then slaughter :)

Grab all items in the staging area and put them in your box. Sell those items and leave the room. Come back in and repeat.
