I've had a few requests asking how I painted the bases for my Emperor's Children, so here it is.
You will need to purchase some Micro Arts Studio Possessed bases. If your FLGS doesn't stock them you can find the easily online.
As always, clean them and prime them black.
Paint the tentacles a base colour of Daemonette Hide. Be careful not to get paint on the rocks as it can be a pain to clean up.
