GroundMan runs down the row until he reaches the back column, or disappears when he touches a broken/hole panel or an enemy. If the enemy is over a broken/hole panel, they will be struck first before GroundMan disappears. If GroundMan reaches enemy back column, he will drop down 3 sets of 3 rocks. Once per set, a rock will always land on the enemy. Each falling rock cracks panel and is Break element, dealing displayed damage. GroundMan changes the panel rocks fall on after dealing damage. Does not spawn if used on broken panels.
