I'm working on a Purgation Squad this week. The Grey Knight sprue is packed with bits. Enough to make 4 different squads. The Strike Squad, Purifier Squad, Interceptors and the Purgation Squad. You only get 2 Psycannons in the box, but I had 2 from a previous box. The Psycannon is pretty expensive points wise but really versatile being assault 2 or heavy 4. Even better is if you pass a psychic test you can shoot these guys without needing line of sight.
So far the silver is done, I've blacked in the details and just started the gold. More from these later on in the week.
I'll be doing a guide on how I paint my armour soon, so watch this space.
