I didn't think I pushed that hard >.> I just helped it to go a bit faster so the attack can go through. Hmmm... Let's try this...*The snow looks like wolves at first, and they begin running down the mountain, but as they are running, they suddenly deform back into normal snow.*
Ok, I kind of lied there lol. Don't just push your chakra forward, or you risk pushing it out of the snow, literally, like you just did. Push the chakra in the wolves forward only enough so that they speed up. After they've sped up, focus the chakra to be how it normally was so that the wolves will stay intact. It's not like if you were going up a mountain, where you would slow down if you start pushing. If you're pushed down a mountain for only a moment, you'll keep that momentum until you go down. Therefore, not only would pushing the chakra constantly be risky, but it would ultimately be pointless.
~I focus my chakra into the snow to make it a constant stream of chakra to make it rise. I concentrate on the shape of the snow wolves and then help the snow begin to move. I then give it enough force to begin the wolves descent down the mountain and focus on keeping it in the shape of wolves. Finally I let the snow wolf led avalanche take it's course.~
