More Rules

OK, Some other parts of the rules that confuse people.
What is the difference between Creo, Perdo, and Muto?
OK, we have to consider that magic is based on Aristotelian and Platonic philosophy. These philosophies claim there is a "perfect" form out there somewhere that everything else is simply a reflection of. Magic is often wrong, but it is powerful enough to win an argument with reality.
Creo (I create) moves things toward their ideal form. Therefor:

1. It can bring things into being. Creo Terram (I create earth) can create silver, gold, and steel.
2. It repairs injuries, as injuries are certainly not part of the ideal. Creo Animal (I create animals) can heal a horse's broken leg.
3. It also makes things as good as they can be, but no better. Creo Corpus (I create the body) can make you a perfect human, but not superhuman. For that, see Muto. It can also mature something to perfection, but not past perfection. For that, see Perdo.

Perdo (I destroy) is the opposite of Creo. It takes things away from their ideal.

1. It can cause injuries. Perdo Animal (I destroy animals) can break that horse's leg all over again.
2. It can obliterate things. Perdo Terram (I destroy earth) can simply make a hole in a stone wall.
3. It can age things past perfection. Perdo Corpus (I destroy the body) cannot age a child, as that would be an improvement, but it can age someone who is already an adult, as that is an impairment.
4. It can destroy aspects of things. Perdo Herbam (I destroy wood) can make an object weightless, as it destroys its weight (but this sort of application is very difficult).

Muto (I change) changes things. It gives things qualities they normally cannot have. The effects of Muto disappear after the spell ends.

1. It can change colors or the shape of things.
2. It can give you powers you normally don't have. You can use this to grow wings on a human, as humans do not normally have wings.
3. It can change one thing into another, like a prince into a frog or water to acid. BTW, the burns from the acid last after the spell ends, but the acid changes back to water.

I might as well fill these out.

Rego (I control) controls things, as long as the end result is not unnatural. Since the end result is not unnatural, you do not have to maintain the spell after the fact. The method can be unnatural though.

1. You can control their actions. Rego Mentem (I control the mind) can let you control some one's thoughts and actions.
2. You can control some thing's position. Rego Corpus (I control the body) can teleport you and your friends to Paris. It is unnatural to teleport, but it is not unnatural to be in Paris, so that is OK.
3. You can make things. Rego Herbam (I control wood) can change a tree into a wagon, as long as all the required parts are present.
4. You can hurt someone with Rego by throwing things at them, or throwing them about, but not by direct manipulation. Toss someone into a wall, great. Grab their arm and twist it off, nope, that's Perdo.

And what about Intellego (I perceive)? Intellego gives you information.

1. You can read minds with Intellego Mentem.
2. You can see through smoke with Intellego Auram (air).
3. You can understand the speech of animals with Intellego Animal.

OK, feel free to comment.
