Sap is epic when maxed out, I make 180 dmg to 130 :lol:
Flash Strike the best, Aggression can make enemies confused, especially against ranged classes, use it and run around fast to make them lose target and Strike with no mercy :wacko:
Parry doesn't really affect me, I always Parry without it, But it's your choice, each level of parry adds +1% Parry, each level Aggression makes mobs focus on you more ( level 1 last 1 second, aggro can be stolen easy :wacko: )
Flash Strike/Sap for me or if you Kung-Fu Panda use Kung-Fu Pow ;D
