No, it's chakra. Chakra is the main thing you need when you want to perform ninjutsu. Now, let me explain my training style. I will post a template which you will copy and fill out each time I post a technique. Okay?

(Fukumi Hari) - Hidden Needles
Rank: D
Type:Attack
Range:Short
Chakra Cost:10
Damage Points:20
Description: The user is able to call forth needles into their mouth and then spit them at their opponent with great accuracy.
This is the first technique and it's rather basic. You summon needles from your mouth and spit them out with great accuracy. Nothing special to it. No need to perform it, just use the template above.
