You can get them from mission, but they will have diferent stats than wild ones (if you're looking for them for DnA) but tbh you dont need to get missions for them, they're a very very common spawn all over Endor.

Land at the northern Starport on Endor (Smuggler's Outpost if I recall correctly). Then head straight north into the northern highlands. They are devoid of trees and vegetation so it is easier to see. Run around this northern hill area and you will see lots of Merek lairs (among others). They can also be found randomly in the forest. But I have my best luck in the north....out of the trees.

I've found several groups of lairs involving Merek southwest of the northern outpost. If your trying the high damage formula, note that adding 2 in agression and 1 in prowess, like stated earlier, seems to produce a CL73... I had enough to try twice, but got hit with a @%^&ing critical failure!
