*I stand perfectly still, taking deep, long breaths. I focus on the breeze, letting it blow around me, let it mix with my body, feeling the wind, savoring the cool strong breeze on my skin. I take a big breath then think about your questions*
Wind itself is simply air that has force behind it, I think. But wind chakra is made when normal chakra is rubbed together, making it thinner and sharper. It can also generate air circulation outside of the body, even use pre-existing wind. Wind can be used as purely brute attacks, using the force of the wind to knock over opponents. Or it can be used by making the wind sharp and deal slashing and cutting damage, even adding this trait to weapons to increase the cutting power. It is strong against lightning, since its a natural insulator. Its weak against fire, but can be used in conjunction with it for a boosrt in power.
