[i]"Aim at an enemy to view its health and other critical information in the scope"[/i] What other critical information, you might ask? When you stay on target for about half a second, those red numbers in the scope all resolve. Take a look at the attached image... The number in the bottom right of the display is the power level of your enemy. In the bottom left is the distance in metres between you and your target, as well as a gauge that fills up the further you move away from your target. When the gauge is full, you are at D.A.R.C.I.'s max range before damage falloff applies. In the top left are two bars, each with a number. These are what percentage remains of your enemy's health (top), and shield (bottom). If your enemy has no shield, the bottom bar will always be 0. Finally, i chose this image in particular because it shows the 'mind of its own' ornament. With this equipped, the symbol in the top right of the scope changes from 'D5' to a little picture of a Vex Harpy. You can compare it to the Vex Harpy I'm fighting in the image. You'll also notice this ornament changes D.A.R.C.I.'s colour from blue, to Vex bronze and off-white, with their trademark red lens in the scope, suggesting a far more sinister and risky AI augmentation! Hope this helps :) *edit A few people are commenting that it's a bad weapon so unfortunately all this info is useless. I'll agree that d.a.r.c.i. is sub-par as an exotic, and agree that snipers need some love overall. But bear in mind that whilst it's a low impact sniper, it has 18 total ammo, compared to 14 for most high impact snipers, where those extra four shots make up most of the difference. It also has a clip of 7, as opposed to 3, which typically means you're only reloading once per boss phase. It also has high stability. You'll get off 14 shots on Calus in a damage phase whereas a regular high impact sniper will get off 6.
