In the Narutoverse: Being one of the basic 5 elements of narutoverse, wind is made by molding your chakra as sharp and thin as possible and is usually close range since it requires lots of precision and force. You can also use wind chakra and channel it into weapons, such as kunai and whatnot, enhancing there abilities and making them more powerful.
Strengths:Strong against lightning because wind is a natural occurring insulator. Also strong when used with fire, but only if both fire and wind are going in the same direction. Can also be used together with water, for additional damage and can be a potentially devastating combo, if both are used right.
Weaknesses:its main weakness is fire because wind, when blown on fire, only feeds the fire, enabling it to grow and feed of the air, thus getting even bigger.
Combos: As i mentioned before, wind with fire is a very powerful combo if used in the same direction, and same goes to wind with water.
Offensive / Defensive: In an offensive way, you can use wind chakra and infuse it into your weapons, enabling them to be more powerful and be able to provide more damage. You can also use wind jutsu's, there are many good ones and if used right, are potentially devastating. Using wind in a defensive manner is pretty self explanatory, you just try to blow your opponent away, or create gusts of wind distracting your opponent and throwing him off his feet or game. Can also create distractions with wind depending on the terrain you are in.
