start out with 80+ aggression and use blood shadow focus right before you say go... always go into a fight with full agg..stay away from using; double scorpion scare, crazed ox charge, they use a lot of aggression and are useless in 1vs1 pvp... practice with just stone monkey, savage eagle and white crane.. and keep stone monkey stacked on your opponent long as you can..ways to regain agg during battle is basic attack, getting hit, and seven turtle blow. for your agg to always be 50+ its not gonna happen if your gonna be successful in pvp.

your 2nd queston..celestial ghost wall you get from instances same with jade emperor (look at the drop lists here in the forums to find which lvls drop where)..any other skills you can get from class master npc or lottery agent using world rep
