The Rock Hills set contains one large multi-level rock Hill, one medium multi-layer rock Hill, and a small Rock model. The hills have plenty of wide, flat surfaces that you can place your models on as they climb over the rocks, or place other terrain pieces on the hill. The sheer back of the hill is designed so you can fit two hills together to form a larger hill, or place other rocks along side of it creating a new shape. The large hill is 9 inches long, 6 inches wide and 3 inches tall at its tallest point. The medium hill is 4 inches long, 3 inches wide and 2 inch high. The small rock is about 2 inches square and an inch high. Broken Ground contains a collection of five different-sized rocks, two fallen tree trunks, a stump, and two area templates. Together on the templates, these pieces can be used to represent an area of rocky and uneven ground that is ”difficult” to cross. Or the pieces can be scattered across the table separately, providing cover and hiding places for your models. The templates have different images on either side. One side shows a patch of rocky ground, perfect for representing difficult ground. The other side shows some overgrown flagstones, so you can use the template and rocks as an ancient ruin.
