The Free Folk are a rugged people, not very familiar with any forms of civilization. They aren't ones to settle down on land & farm. They get their meals through wits & wile, making traps & snares to hunt prey. On the battlefields, these snares can just as easily cause issues for enemy troops as it can for tonight's dinner.
The Free Folk Trappers Unit Box gives Free Folk Commanders a new option for their armies. Lightly armed & armored, the Trappers are well-versed at harrying tactics. Able to deal wounds directly to enemy units via their Hidden Traps order, they can greatly disrupt an opponent's plans. & being Insignificant, they aren't worth victory points when destroyed, allowing Free Folk Commanders to use them more dangerously, without worrying about giving them up to the enemy.
