You say so far like either you want more, or want to stop. Hehe, but I'm just getting warmed up. Ready to combine all my questions? Because I've gather enough information I'm ready to start testing the full limits of your theory with hypotheticals, if you don't mind. But first, one last question.
Use of mana to length or prolong life. Right we've all the heard about how mage can live hundreds of life times, using mana to healing themselves and basically rebuild there body from the ground up as need. So in theory, couldn't you use it to boost your natural skill with magic? Again this is assuming they have the forest and knowledge of how to do the alterations just not the capable skill, however afterwords they will. The question is this, is it capable for the mage to alter themselves to increase there natural skill in magic through magic? If so what are the limits of enhancing ones body through magic?
Quantum State: Unknown
Excuse me, but I was temporarily unable to do anything creative. Anyway, on to answering your question!
Well, firstly, magic is not mainly done in the body. The body only helps that soul manifest in reality. It also gives someone greater control of their aura (which mainly stems from the soul, but a person's essence also lingers in hte rest of their body, so those parts can also help shape their aura). Moving ones body can aid the composition of mana in a scale larger than the actual structures (unless they're really big). Basically, when you see a mage swirl their arms around in magnificent patterns, they are not channeling energy through their body; they are giving shape to mana outside of their body. However, the main part where magic connects with the body is the mind; you have to be smart enough to know how to cast spells.
So that was the relevance of the body - as you see there is not a whole lot to improve upon. What really matters is the soul and ones aura. In the soul, complex thoughts are generated and enough magical willpower will make a ripple through the aura, affecting the reality in the area. So what the main part of magic basically comes down to is a combination of creativity and intelligence, a powerful aura (large and dense) and this vauge magical willpower, which IS the main thing when we talk about magic. This is probably the hardest thing to explain, but I did try to go into it in the original post.
So ones body can certainly be enhanced, but this has a limited effect on the increase of magic performance. Increasing ones own magic through magic? Not so much. However, don't forget rule #1: nothing's impossible. This is simply very improbable, even in the forest. Imagine someone never having constructed a wooden desk before, and now they are presented the wood and nails required. Having three giant hammers (representation of the forest) doesn't make it easier than with a single little one.
However, a very intellgent and incredibly powerful master-wizard should be able to increase the power of another mage through pure magic, because in that case there's actually a source of great magic where the enhanced power can come from, rather than a young lad not knowing what the hell to do. In the end, the best way to increase ones magic is through hard training - the very act of performing is probably one of the few things you can't cheat on, simply because it's simultaneously so close to mana itself, yet so difficult to understand.
Nothing in life is ever free, nothing worth having or doing anyway. Doubly so with knowledge and power.
*Rubs hands together evilly* Now then, I want to give you a hypothetical situation and see what would happen before moving on to more questions.
Two rival mages have both found our forest and are now going to kill each other for it.
Mage A has escaped death by finding very good young mages and taking over their bodies via destroying and overwriting there souls before they are very old. Thus allowing him to build up lifetimes of experience. He specializes in both high leave mental magics (e/x the body switching and such) and creating new magics from the ground up. He is also very poor at physical fighting if it comes to that, and elemental/combative magics. Well call him Raven.
Mage B. Mage B is almost as old as Mister Raven, but refuses to basically kill another to prolong his life. So hes extended his life though magic and his physical abilities to use weapons. He specializes in combative magics, but can't do mental types. However is very good at defending against and blocking them. But he can't do anything while blocking them. It takes his entire focus. While unable to actually create new spells he is very good at inventing new ways to use old ones. Such as, using creating a arch of lightning to to now only static charge a sword but also make it extremely hot. Or using a fireball to create fog and the turning the fog into basically a net of razor sharp ice crystals the person has to walk through. We'll call him Maxium.
Begin battle. Mostly, I just want to put the limits of your theory to the test in a real situation. Before I move forward with questions.
