ok mine wood be like a last resort jutsu ever one can use it only if you can master the hand signs and it takes a lot of Chakra
what it dose it takes the clods of the sky and hardes it up and its harder than steel
and it goses down on the emey
(kind of like a ka ma ah ha from dragonball z but not beamish
and not from the hands but from the sky)
so its more sninkish but it takes some time so like i sead
its a last resort.
