This simple mod is designed to make this unit see "a little bit more use" in the game.

Now all the Heart structures (Glades, Tropic, Arctic, Blight and Volcano), the Spring of Life, Creation Nodes and Shrine of Earth Mother would be also defended by Ancestral Spirits.

As a bonus now you have a chance to recieve Ancestral Spirit as a reward unit in the Spring of Life.
Enjoy!
