Firstly RE: Skill bar.
I hate bladers like that, who just do constant KD, stab, KD, stab, KD stab. They wont kill anybody like that, even force blader cant. (I know its not your char, im just in the mood for a rant).
Secondly, as somebody else said the lowest one is the the devil skill, and the one on the right row is the back accessory. But as somebody else said, you cant use it with Devil Wings or any other 'flying' suit.
@ DrFantasy; No offence mate, but 241m is hardly anything these days. It might be alot for you, but it wont even buy you a decent set at the cap, and you could probably get it for $20.
If you wanna see a large amount of gold, ask RedBlueGreen for a screenshot

my skill bar is like that because i have my vital spots on F2 and chains i uses the spots and chains until i get division and impotent and bleed from the frist book cant remember its name then i proceed to KD stab if there not dead lol
