First batch from Soul Wars, the Chainrasp Horde
for the base "ghostly" part I pretty much just primed them a very flat black and then dry brushed them with Uluthan grey. It's what I've always done with my Nighthaunt stuff(not a fan of green or blue ghosts), though for these I left a bit more paint on the brush for the dry brushing and switched to the slightly lighter Uluthan from Administratum grey to get some more contrast and I think I like the effect better.
