I have stage 1 sharingan but doesn't know how to use it yet properly in battle
Alright then.
According to Bianca's KG restrictions:
Description: The user's eye turns blood red, and gains an extra pupil, or tomoe within each eye that will surround the original, centered pupil. When active the user now has the ability to track speeds that normally cannot be seen by the regular human eye.
They also gain the ability to see through visual D rank genjutsu and can predict most taijutsu and ninjutsu movement and technique, allowing one to be able to react best to the situation.
That is what your current stage of sharingan can do.
Now then, to test it.
The first thing that your current stage of sharingan can do is track speeds that normally cant b seen by the regular human eye.
*Kg x1*
The clone begins running like Rock lee without his leg weights.
Track his speed, and destroy him.
