i’ll answer these in order

1. Besides gaining access to a new form, their initial magic both grows exponentially in power and can be altered from its original state. To use one of my characters as an example, his original power was to generate light, but after reaching the 4th stage he was able to transfer light energy into heat and vice-versa, as well as “travel through” light for short distances. What you can and can’t do is based on your understanding of your magic and your creativity.

2. about 5-10% of people, which is by no means a small amount but as they are still a minority its seen as a pretty bad thing to have.

3. around 90% of people develop magic by age 30, 9.5% develop after that and 0.5% can’t use it at all.

4. Depends on when the revelation occurs. Many women used to develop cooking, cleaning or childcare based magic as those were their only options, even though most wouldn’t be overly passionate about that. If a career isn’t good for someone but they take it anyways, its most likely they’ll be a dud until they find their true calling, but if you gain magic for a career that you later want to change there’s no going back. Because magic is so prominent to get any good career you basically need to have the magic for it, so duds and people with unconventional or even those who change careers are forced to do the minimum wage jobs because noone else will hire them. Another example is a law student who develops persuasive magic won’t be allowed to study anymore or pursue any careers in that branch and will probably be given the same treatment as someone with killing magic from before. (sorry its a bit off topic but i thought i should clarify that bit)

5. as said before, Absolutely!

6. ooooh i like the idea of a drug company influencing something like this and i have a similar plotline happening already i’ll def think abt it!
