Very nice technique I must say. You use the technique to breath live to elemental techniques giving them the ability to act on their own. I think this is great but the amount of usage is small.
It says the size is half of the element. Does that mean if I use this on grey stone golem, the size would reduce to half? If this is used on an elemental techniques that is normally not in the same of something that can move, would giving it sentience make it able to move and still use jutsu from its source?
If the sentience technique uses a technique, would the chakra be deducted from its 300 chakra pool and what happens when the chakra is used up, the sentience stops or the technique ends?
What if you used this on a technique that requires your chakra to sustain, would you still need to fuel it with chakra or that stops since its now sentient?
Can you give live to natural elements? Like a tree that is not made by mokuton jutsu? What rank would they be and would they be able to use jutsu from their respective elements?
Usage amount is small?
How many sentient things do you wanna make?
Yes, the item you create would be half the size, so the golem instead of being 100m would be 50m tall.
No, for example, if you made a sentient swamp, it would still just be a swamp. It can use jutsu from the element it's made up of, so this swamp could use earth jutsu to reshape itself and such, but in general, it remains as it is. It's better to use it on say, a water dragon, something already mobile.
The -10 per turn comes from the user. Jutsu used by the creation comes out of the 300 chakra infused into it. It uses chakra from that pool to form it's own jutsu. When that pool runs out, the creation/sentience ends. This would also end if the being is destroyed.
If it takes a chakra per turn to remain on the field, that will still come from you, as you're paying 10 chakra per turn to keep it sentient, the pool just allows it go act on it's own.
No you can't add this to a natural tree due to this "The user is able to use his Yang nature to embue life into an elemental technique ", it has to be a technique, that you create.
They can use all jutsu you know for the source they are created from, regardless of rank, following logic and restrictions
