Been keeping this one secret, but I have another new skill for the next update to go along with the fencer.
This skill, the Farter, causes the lemming to stop for a second to fart. Because the fart smells bad, it also causes other lemmings to attempt to move away from it. The fart lasts 5 seconds before exploding, with similar effects to a bomber.
Will give some screenshots / an exp build later today.
