Magical Writing The purpose of writing something in a magical way is not to make it legible to Other Beings. Those beings don't need to read, since they can understand what you are writing straight out of your head. In my experience, there has been no difference between a spell written in Hebrew-based script (like Enochian), Latin-based (like Theban), Runes, or plain old English.
The difference between a magical script and your native script amounts entirely to how much concentration it takes to write it out. You don't think too much when you are writing things out in the way you write normally. Those people who write things out in a style unfamiliar to them channel much more power. So writing something out in a different way is the key to making a written spell powerful.
One way is to create a magical alphabet from whole cloth, whose letters correspond with the letters of your native alphabet. This is what I have used for years. My best girlfriend in school and I used a secret alphabet for passing notes, and that alphabet is what I use for written components of spells. The major drawback to this is if your native language is Chinese. Written Chinese uses a sophisticated system of symbols which represent ideas, not sounds, and these symbols evolved over such a long period of time that it would be impossible to create a system of meaningful substitutes. In that case, it would be advisable to write out the sounds in Roman script.
Another way, which works with any writing system, is to write everything backwards. This does not mean just assembling the letters or symbols in reverse order, but to also write the symbols themselves backward. Again, this would be difficult for Chinese writers, but not insurmountable, and I would expect that the concentration involved would be quite high, thereby making the written spell possibly more focused than one written in an alphabetic language.
There is one other, novel approach to focusing on the writing of the spell: typing. Touch typists like myself have actually learned an alphabet based on the movements of our fingers. It's as familiar to us as writing longhand, and for some of us touch typing is more familiar than longhand. Those who have never learned to touch type however will find that typing a spell out requires a lot of focus. This would be a method that works best for those whose hand function is greatly diminished, as long as they can hunt and peck. Can you imagine the power that Stephen J Hawking would have if he delved into written magic? He writes entire books, although he has lost all ability to move his hands and speak with his mouth, by a sophisticated computer system that tracks the movement of his eyes toward letters on a visual keyboard. It's no wonder, magically speaking, that his books are so successful. Stephen King also never learned to touch type: he hunts and pecks out those novels. From a magical point of view, this imbues great power into whatever is written, so of course whatever he writes will be successful.
Take some time to experiment with these methods of magical spell-writing and see which one comes to you the easiest, or which one yields better results. If you are a newbie to witchcraft, try writing a simple wish out and then releasing it to one of the elements (Bury it, burn it, shred and toss into the wind, or flush in the water). Use a different wish for each writing method and make them small wishes (I find money on the ground tomorrow, I get released from work early on Friday, my partner/parent makes my favorite meal within the week, something dumb like that). Use the same release method for each (shred all, burn all, etc). See which one comes true and comes true best and/or fastest, and that will be the one you should use. Example: if you wish to find money on the ground with a system not suited for you, you may end up finding some small change but nothing remarkable, whereas if you used a system that suits you, larger amounts will find their way to your path.
Always make sure you are having fun while working magic! If it seems like work, it won't work as well as if it seems like a game. Enthusiasm is more powerful than a diamond-tipped golden wand.
