Footbomb 2 is a second version of the Footbomb skill, instead being an american football ball. It works in a similiar way, but it doesn't roll around as much and it bounces once after being kicked. It deals moderate damage.
On level three the bomb doesn't explode automatically; it instead needs to be touched, kicking it forward before exploding shortly, although the target can also touch it to fling it back at the sender. It never despawns by itself, which means there can be unlimited bombs at a time, as long as none of them are touched.
