User blog comment:Krauserlols/Is Riven a real Wind Master?/@comment-24103712-20131217135902

Riven didn't master the wind technique, but she knows it. the broken wings ability may seem like a normal blade combo but if you recall Yasuo's Q two normal attacks then a knock up. Riven's Q two normal attacks then a knock up. Wind slash says it in the name "wind slash."

Riven never mastered the wind technique but she knows it and now uses a fusion of the wind technique and the ki technique you can see in her other ability's.

P.S. Janna has mastered the wind technique to.
