This build is used for the versatility. If you get tired of a single type of play style you do not have to make a new build you just have to change the weapon choice. I use the claymore due to the the high strength and dex stats. The spells are used at your discretion and you can change between both sorceries and miracles or a combo of both. I use crystal magic weapon because of the higher damage output made by the hugh magic adjustmwnt of the tin crystallization catalyst.
