1. Heavy Thrust-> Internal Release-> Fracture-> Phlebotomize

Using Heavy Thrust from the side will give you a damage increase and should always be active, internal release (pugilist) increases Critical Hit Rate, Fracture (marauder) and Phlebotomize will add Dot (Damage over Time)

2. leg sweep-> impulse drive-> disembowel-> Chaos Thrust

Leg sweep is a cool down with stun effect. I place it inbetween the combo for when I am solo. Stunning the mob allows me to get behind them for impulse drive. With limited options on PS3 controler it is now habit. The “Chaos Thrust combo will also generate Dot and lower piercing resistance. Impulse drive must be from behind to activate the combo and generate the buff/debuff.
