When you head down the path of Darkness, as a Dark Eldar player it is worth exploring to it's full extent. Darklight weaponry is uses an unknown substance sourced from Black Holes, Warp Storms, or other clestial phenomena of great magnitude to cheat the laws of physics. Even to see a beam of it fired will leave permanent damage to the retina.
Back in the day we had Dark Lance spam like crazy. It was all over the place, and really only one a maybe a couple builds that were even possible. It was effecient for Dark Eldar, but was it competitive?, no. Is it possible to continue this way of thinking to make an army now in 5th edition with our new codex? Probably. So its what I sat out to do. However, with our new codex I was not as limited to the Dark Lance, so Blasters are included as well.
The first thing to figure out is that it takes on average 9 Darklight shots to kill a rhino. That would be 6 hits, 3 pens +1 glance, and it general it takes 3 pens to kill a vehicle. So with that in mind, how many tanks can you blow up in a round with Darklight shots. The answer comes down to almost 6.
This list has in it, 51 Darklight Weapons. Many of the units come with 4 or 5 in each. While I know that I can get more into the list, the Archons with their BS7 will pretty much always hit, and therefore worth the 75pt blaster. This list is an excercise, and while it may work on the tabletop, it was not designed to. However, a couple tweaks, and you may therefore come forward with a list that might work for you. It is awful spammy for myself.
