That one doesn't work.

Does it work if he tries to cast it normally, or is it spent?

 What if he puts the spell into two different pieces of paper? "Wind, come forth!" and "flow and fly as my will commands it!"

The paper was not spent remotely, and can be used.

Two different pieces of paper with different pieces of the spell make it stronger and better still.

Yes!

He tests this property again by breaking it into three pieces: "Wind, come forth!", "flow and fly" and "as my will commands it!"

Better still!

Ok, so he is going to.

His mom call his for dinner, and then asks him to watch some TV, which Temple decides to actually do, just in case his "mana" can get to full again. But before the movie starts, Temple writes the first wind spell down.

Two hours later he gets back he tests the nearly two-hours old wind spell to make sure it didn't lose power during that time.

Then he starts writing the words "Wind, come forth, safely flow and fly as my will commands it!" in individual papers each, casting the spell afterwards.

All papers are consumed, and the spell is noticeably but not significantly stronger than three papers separately.

Maybe it was a result of the word "safely"? He is not sure is worth it to repeat the test with the same spell, not while his mother is at home.

Next tests. Figure out if he can get away with subtracting or adding parts to the written spell.

(Maybe Temple should just call them scrolls. You are wizard now, Temple. You have magical scrolls)

First, he writes "Wind, come forth, flow and fly as my will commands it!" and tries to cast the magic by just saying "Wind, come forth!"

First-and-a-half, if there is still paper left from the first test, he will use the words "flow and fly as my will commands it!"

Second, he only writes "Wind, come forth" and says the full "Wind, come forth, flow and fly as my will commands it!"

The first spell works weakly but doesn't consume the paper, the first-and-a-halfth does not work, the second one does.

And how does the second test compare power-wise?

Stronger than just "wind," weaker than fuller sentences or more papers.

What if he tries "Wind, come forth, flow and fly as my will commands it!", which he is just going to label The First Wind Spell (TFWS for short), leaving the "it" but speaking it out loud?

Works but doesn't consume the paper.

Uh, maybe it is a grammatical problem? Temple didn't even consider that each scroll needs to make sense by itself.

Can he add "it" to the incomplete TFWS scroll and cast it normally?

Yep.

Ok, next series of tests, calling the aid of various things to see which ones count as valid.

Then he will write multiple scrolls of "Wind, come forth", "flow and fly, as my will commands it!" and a set of various scrolls following the formula "by the power of [words]," where [words] will be any of the follow: Sky; Zephyrus; Boreas; Atmosphere; Moon; Sun; Mercury; Venus; Earth; Mars; Jupiter; Saturn; Uranus; Neptune; Pluto; Jesus; Buddha; God; Angels; Heaven; Magic; my words; my voice; my magic; the elements; and then various wind deities until it is time to sleep. He will keep safe intervals between, of course.

Then Temple will cast them using the following pattern: "Wind, come forth"+ "by the power of [words]" + "flow and fly, as my will commands it!"

Well, his sleep time will arrive before he's done even writing the "Sun" paper, but if he's willing to spend about four or five days testing those combinations he might be able to do them all.

Temple will do the batch he got (that goes up until "Sun") and experiment with those before deciding what to do next. He will experiment with those after school.

He wakes up early and the first thing he does in the morning is to sit bolt upright in bed and cast the TFWS. Relieved that it wasn't a dream, he then looks at the clock. He definitely could sleep some more but...

...Well, he could use this time and cast a spell to fix his wall.

He composes the following scrolls:

"Earth, come forth with your stability!"

"Water, come forth with your adaptability!"

"Change the pigments of this wall!"

"Safely undo the effects of magic gone astray!"

"As my will commands it!"

Then he casts the spell.

Lookit go! All neat.

Eeeeee! He can do magic! He will proceed his morning routine with a spring in his step. His mom asks why he is so happy and Temple just replies "the world is an amazing place."

He woke up early enough that he should be able to perform a couple of tests before school. What happens if he calls upon the power of the Moon or the Sun to aid his magic?

Well that depends on what exactly he's doing.

He wants to see if there is any noticeable difference when using: "Wind, come forth"+ "by the power of Moon" + "flow and fly, as my will commands it!" or "Wind, come forth"+ "by the power of Sun" + "flow and fly, as my will commands it!"

The first one is much more powerful.

That is weird... and his mom is calling him to go to school already. Sigh.

Okay, he can go through the day of boring institutional education, motivated by knowing he will be able to cast magic after school, sure.

This is gonna be a long day.

Okay, between classes he will just cast a simple spell in a quiet corner, just keep the practice. What happens if he calls upon the power of "Sky" instead of the "Moon"?

About as powerful as when he calls the Sun.
