Its very powerful, but when you get down to it, other then the trick of converting incoming attacks, its really not that different from Yamato's wood - they both have the ability to create something and they apply that ability to a variety of purposes. And like Yamato, it seems to take a moment or two to create anything of significant size, giving your target time to dodge.

As for chakra, it could simply just be a very efficient technique. There are situations in the real world where introducting a single crystal can trigger a massive crystalization chain reaction. If the technique works on something similar to that, creating things from crystal could require very little charka - controlling them once they exist (like the dragon or the clone) would likely take more, but she didn't do that all that often.
