Dark Reapers. Restricted to 5-man squads, they still work really well against Marines and Marine equivalents. They get two shots each, high strength and ignore Power Armor. This is enough to make them a nightmare and a priority target for Space Marine players. I fitted my Exarch with the Eldar Missile Launcher (yes, I'll make a Hurricane Launcher variant as well ... later) because he's the only infantry unit that can carry a vehicle-mounted weapon... and not on an anti-grav platform either. That's a whole different class of badass, people. Anyways, this Exarch is rather selfish when it comes to his Exarch abilities. The other Exarchs at least have one ability that carries over to the squad they're attached to. Not this guy; Fast shot allows HIM to shoot twice, and Crack Shot allows HIM to reroll to hit (and ignores cover saves). Frankly, he doesn't give a damn about really teaching the other Dark Reapers. He's more of a "watch and learn" guy.
So, primering the models black does a lot of my work for me as now I only had to highlight in grays for the black armor. Bone colors were done with foundation paints (Khemri Brown, I think), then hit with a brown wash, and then worked back up to bone using multiple layers of a glazed Bleached Bone. The glaze was made by watering down the Bleached Bone paint, then adding the tiniest amount of PVA glue (Elmer's to us Americans) to make sure the solution doesn't separate into the cracks like a wash. The guns were made with Liche Purple, then worked up with first a Warlock Purple glaze, then a 3:1 Warlock Purple-Bleached Bone glaze. Dark Reaper Hair was simply Liche Purple, followed by a black wash, then picked out with Liche Purple again for the highlights. I didn't want the hair to stand out too much, otherwise I would have lightened up the highlights some more.
