Shadow's rejuvenation allows you to permastealth with just D/P. By using the black powder+heartseeker combo you can regenerate all the initiative that you spent. This is done by using heartseeker to gain stealth right after the stealth from the previous heartseeker ends.
Since black powder + 2x heartseeker costs 12 initiative, with 2x shadow's rejuvenation procs(6 initiative) and the 6 initiative gained naturally during the 6s of stealth that the combo gives, you end up not spending any initiative.
Here's the steps to make it work:
1. Use black powder to put a smokefield on the ground.
2. Use heartseeker in the black powder to gain stealth. This grants 3s of stealth and gives you back 2 initiative from shadow's rejuvenation since you entered stealth.
3. Use a second heartseeker right before the stealth from the first heartseeker ends. By timing this correctly, there is a very small window when you are not in stealth before you gain the stealth from the second heartseeker. This procs both of the initiative gains from shadow's rejuvenation which gives you 1 initiative from exiting the stealth from the first heartseeker and then an additional 2 initiative from reentering stealth with the second heartseeker.
4. Use black powder again when the stealth from the second heartseeker is about to end and repeat the combo. Since black powder only lasts for 4s, you can only get off 2x heartseekers before it ends.
Here's a video showing how it works, with good timing you can be out of stealth for a short enough duration that the enemy does not have a chance to retaliate:
