How does it work?
Maintain all your DoT's and use Consealed Weapon and Merciless Resolve as much as possible. (dynamic playstyle)
Below 25% enemy health: cast Impale instead of Consealed Weapon and don't use Merciless Resolve and Dibilitate anymore. 
Below 10% enemy health: cast your DoT's one last time, then only cast Impale. 
Tips: 
For more initial burst damage, you can use Shooting Star on your backbar instead of Incapicitating Strike. 
Optional: 
You can use Relequen instead of Null Arca in case you don't have Null Arca available in your gear collection yet.
