Hopefully I wouldn't be your last.
From who did you learn blast release?
What I know about Blast release?
"Blast release also known as bokuton is a trademark ability that gives it's user the control over the explosive properties of a solid material or make a solid material gain explosive properties, in other words enable the user have the energy in the form of chakra needed to excite another source of energy or state causing it go erupt mostly in a violent vigorous manner. It is mostly used in warfare, though it can be applied in agriculture and mining. Blast release is applied or invoked when the user is able to infuse their chakra into the material unlike some other ability that simply just looking can get the job done. It was only seen used by members of the Iwagakure especially the Blast Corps, one famous user of this hidden ability is Deidara (hope I spelt it correct) though his own style was on a whole different level."
What makes Blast Release awesome?
"Well imagine causing an explosion to occur in a town square and you are at the middle of it and for some reason you come out untouched (that is because blast release allows you the user to control the direction of the explosion) Plus it can be done on just about any tangible substance."
YOU ARE A WALKING BOMB!
Performing:
I mold chakra and transfer it to my hands then release it outward through my right hand that is stretched out and facing a safe direction from us, as the chakra is expel from my hand it produce a violent yet controlled small scale explosion that seem accomplained with a force able to push back or repel projectiles, I repeat this process with my left hand then again with my right hand till I got used to it.
Strength/Weakness:
As for strength; it doesn't require hand seals, it is almost unpredictable, does not block my view (maybe briefly) and has a wide range of attack.
Weakness; it has a short reach, and can only be produced from the hand (correct me if wrong here)
Application:
I will use it to push back a kick or punch attack (weaker rank ofc), destroy a paper tag, cut off a chakra line or rope, knock someone out...
