I love the Hârnmaster world setting. The rules aren't the easiest ones but supports the setting fine. Hârnmaster Shek-Pvar (Magic) is a coherent rule system for spells and magic items. A lot of focus is on players designing their own spells and the existing ones serve more as examples than a finished "grimoire". If you like the magic of Tolkien or GRR Martin, you will enjoy this. If you're more a boardgame/class level/d&d player this might not be what you're looking for. Strongly recommended, if not only for the new interesting take on magic and spells.
