It used to be 3 colours minimum.
I would like to use my Delves in a 1500 point battle on Friday.
My Hydra is not undercoated, and my Spearelves are not undercoated (they also consist mostly of those old unipose HE spearmen, and 10 old menghils manhide flayers)
Is this going to be a problem? I know I should paint them, but I don't have a garden/anywhere to spray models. I am going to spray them in the garden of my friend who I am playing after the battle. (as long as it isn't raining)
