I was bored so I tried to solo the Headless Horseman with my pally twink.
After two or three attempts I finally got him. It's actually not that hard (as a ret pally) and you don't need uber imba skill or equip.
It was the first time that I skilled my pala ret and so I killed him wearing half melee/half healing gear/enchants. Ah and because I had too much time and nothing to do, I created a pointless intro :D
