I know of the witch you speak of, but no longer have access to the magazine to attempt a direct conversion. Even if I still am in possession of that particular issue, it is in a storage box with countless other Dragon's and inaccessable.
My personal witch class has used some of the elements from that witch but also expanded to include some of the works from other sources as well as making it a Template class that allows the witch player to choose the type of witch they are. For example some witches may choose to follow candle magic, some use athems for blood magic and cauldrons for potions, while others may not use any of these or only one.
The current problem I have with all exisiting witch classes is that they keyhole the archetype into what the particular author sees a witch to be. As a student of religion and magic, I have spent quite a bit of time studying various forms of paganism and know many pagans. Very few people that I know, and that call themselves a "witch" practice the same exact same version of the "art", unless of course they are Wiccans which isn't truly a pagan witchcraft anymore. They are technically following a specific form of witchcraft, but they have evolved into just as much a formalized and organized religion as any Judao-Christian religion. That fact alone is really an antithesis of witchcraft which is supposed to be individualized and personal.
