*I take the scroll again and and focus fire chakra within my body. Then I channel the gathered chakra through my arm into the scroll and manipulate it so that a tiger made of flames is released. I direct the tiger towards your clone and it attaches to him as soon as it is in range. Then I cause the tiger to explode, while still attached to your clone.*
The purpose of this...? Hm, if the tiger is sort of hugging your clone (xD) it would make him unable to counter this or any following technique... Other then that, the damage it causes, when eyploding, should be so massive that your clone would disperse. And I doubt that any opponent would be able to survive it

So I gues the purpose is more likely to deal as much damage as possible, by affecting the whole body.
The battlefield, if flammable, will be incinerated. If it's not flammable the explosion could cause a crater, depending on the material the ground is made of.
The explosion should also be pretty big and affect a huge area.
