The best advice I can give about using magic in a fight is don't. Magic can be difficult to use properly, especially in a stressful situation, and if you fail you will have wasted your energy. I would only recommend using magic to prepare for a fight, perhaps setting up defenses or personal enhancements that you can activate in an emergency, though I'd hope you were living someplace where you wouldn't need to worry about that sort of thing. Your number one focus before a fight should be preventing it, and you number one focus during a fight should be ending it while coming to as little harm as possible. Magic is not well suited to personal combat, I would recommend martial arts instead if you must defend yourself.
This is the best advice I can give you. If your ever threatened by a person or animal coming in your direction focus your energy into creating something like a shield and imagine a bunch of strait lines of every color you can think of coming from you connecting to the shield and shooting at your threat while the lines are still connected to it. This should usually cause confusion in your opponent or fear or something like that. It's meant to avoid fights and I'm sorry that the best I can describe it.
I got one on this website http://www.spellsofmagic.com/spells/spiritual_spells/defense_spells/4520/page.html here is a spell name as Divide an object. So my i request to all experianced magician that try this spell and Please share your result on this thread. Please........
To me, this particular spell sounds unlikely to work. Magic requires three things: faith, focus, and energy. To effect physical force upon an object is not only very difficult but would likely be very tiring. The best uses I've gotten out of magic are things that only magic can do, astral projection is one example. As such, the most effective means of magical attack are ones that approach the enemy from angles they cannot defend against, such as their mind. Ideally, you could use a spell to break their concentration, leaving them vulnerable. However, it is possible that you will be equally vulnerable while you cast the spell, since you are taking effort away from the fight, and you may have to fight against their focus to infiltrate their mind to begin with. I wouldn't recommend doing this without having practiced it many times until you have refined the technique just as you would need to with a martial art.
Yeah, if an angry animal or person in coming after me they are more likely to get a fist to jaw then killed by my electric figures. Id agree with taking martial arts. You might want to try researching energy manipulation. Its theory of course but as magick is energy, you would think it possible to form negative energy around your hands before making contact. Give the energy a purpose and it might work similar to a hex. Again, this is theory.
As state, magick wont be much help if you tried to directly fight a physical person with it.
However the best way to go about using magick and fighting I believe is to effect your mental state. For example using magick maintain a calm mind during a fight.
The closest you come to actual combat magic, as in within physical combat, would be concepts revolving around Chi within the martial arts, the Beserker concepts within Norse magic, and similar such ideals.
Given the rapid and immediate nature of a fight, these aren't spells. Mere words won't do anything (unless you're talking yourself out of a fight) and there is no time for ritual - not that ritual would do much of anything beyond implement a subconscious influence anyway.
Using your chi can help you stay fluid, help you stay strong, can help you be aware, help you strike faster, so on and so forth. To achieve such things often requires years and years of study.
