"Remember where the vital organs are." Viktor points to the throad .
"Slice this, and your enemy will suffocate from his own blood".
Viktor points to the liver.
"Strike it, and you leave your enemy for a slow and painfull death"
Points to the lungs.
"They are protected by the abdomen, it needs a heavy strike to penetrate through it. Two hands are needed, making it look like hammering a nail into a wall, only it's one brutal strike. Strike it, and your enemy will suffocate too. But there is a way around the abdomen, takes a longer blade. A dagger works here, you need to go from the stomach into the tip of the lung. This move is best done from behind your enemy".
Shows the deep cut.
"Goes from neck to groin. The combined damage of the neck, lung, stomach and groing will kill your enemy quickly".
Then shows the uppercut.
"When you have a longer blade, and are a strong person like James, you can penetrate the skull and stab the brain. Instant death. All these moves require only one secodns each. Now try it again on my mark.
Common. One, two, three, four, five six."
On the second time, Ashley is still not so good at it. On the third its slightly better, on the fourth it's better, on the fifth she does it perfectly.
"It took me a month to remember all these in medical school" - pointed out Vik.
"Use these six attacks if you need to quickly kill your target without raising too much suspision. You don't have to do all six, only one is enough."
