In that case Treesinging is useless.
Woods are the only possible target for the "move terrain" part of the spell.
And the damage part requires a "Forest or a similar terrain feature"
If neither of those conditions is true, Treesinging cannot be cast.
Use Light, Beasts, Metal instead of Heavens
NecroLords: Use at least one Death Mage
Brets: Use Peasants&Damsels
Skaven: Don't use Skryre SAD
Teron is right.
treesinging has only effect on "woodlike" featuers. So if there aren't any, than we are having a bad day.
It think it makes sense rule wise but I dont think that they meant it for the spell to do only that because that means you can only only play on one kind of table and any other kind you play on you lose. So I think its okay to use it on other features im not sure tournament wise but in a friendly game I dont think anybody will say anything.
That's why we get the free forest terrain for pitched battles. But hey, we can't always have it our way.
also, if u read wood (tree) singing further down, it said you can do d6 str 4 atks (or d6 str 5 atks if in forest)
vampire counts = magic and black knights wrong!
