A good description is in JoS Azazel's Astrology section. Check it out!

Scorpio in Mars gives a strong-willed, intense, highly sexual energetic and tough nature. It is an extremely powerful and healthy working aspect and gives the person a talent for black magic and spirituality. These people are not easily angered, but if they lose their patience, the consequences can be unpleasant.

Ok I will

long story short: don't go too obsessed about it,
as it's a precious gift for people like us it also can consume you to the last drop!
and always remember that the misuse of power have a horrible consequences.

So I'm one of Satan child who posses a talent for black magic does that mean my aura is stronger then most physically n spiritually

it's a limited perspective to see that the Entire Aura is determined by only one placement or aspect of your chart

What do you mean explain it

as far as i know it's affected by:
-all your chart placements and aspects (which requires very hard work and integrity to fully understand all of them).
-the current placements of the planets.
-your current mental and emotional status.
-if you having a specific connection that boost you (can't count on that forever)
-and MOST IMPORTANTLY your work on your soul and meditating
(which may lead to transcend all the above)
