In Ironhide’s words

The Ironbark Treant has two modes. While rooted, it works like an artillery tower, slamming the ground with its huge fists to crush every enemy nearby. Sounds familiar? Yes, much like the Weirdwood from Kingdom Rush Origins. But now you can also uproot it and send it walking onto the path, where it blocks and fights enemies up close.
So when the heroes pass through the grove later in the campaign and lend the treants a hand, these old guardians will gladly return the favor.
