Well, I have my second miniature group ordered now. I have added the following, which will make a playable army somewhere above the 500 point range so I can begin testing.
2x boxes of Wytches
These are really just filler pieces to make it a legal army. There are a bunch more things that I am likely to need to convert or buy multiple boxes of to complete. The force after wave 2 (no grear) looks like this:
9 Wytches in raider
20 Wytches on foot for portal
2x 6 Bikes
Again this is a partial force, but I plan on getting some Hemonoculi as a second HQ and dropping the Archon. I will need more warriors to get the bits for a Trueborn tank busting squad, and I need to convert 3 bombers and a parasite engine or two as the anchors of the list. So far so good!
