Number of casts: 18. Difficulty: Medium. This design is taken right off the Hirst Arts website. This piece is a fair size, over eight inches in height. The base was MDF, the hill styrofoam. You really need to use a form to get the walls to square up (I use legos), and make sure you don't try to build too much at one time. It is a useful design, one of my favorites, however because it gives your table a great looking castle without taking up too much space. I recently updated this photo with a new tower which incorporates pieces from the Gothic Dungeon and Gothic Arena molds.
