Death from Above: Takedown

All takedowns are the same, only each one is specially designed for a certain playstyle, they always have at least 3 steps:

1. You jump onto someone from at least 5ft. 
2. You push your target down on the ground as you cover their mouth. 
3. You have 2 choices, either: You stab the target in the heart killing them instantly, or you can take 6 seconds to choke them out by putting your hand on their neck. 
4. You step off the body, if you successfully perform this Takedown, you take no falling damage. 

This takes a Full Action and it doesn't Alert others.
