Desolate Heritage

Your creatures have Battle cry.
If they already have Battle cry,
then this acts as a +1Battle cry.

Thus saith the Lord: In an acceptable time
have I heard thee, O isles of the sea, and in
a day of salvation have I helped thee; and I
will preserve thee, and give thee my servant for
a covenant of the people, to establish the earth,
to cause to inherit the desolate heritages;
-1Nephi 21:8
