Naruto Chapter 522

[Sam98034]

someone should make a count of the elements...

5!/(3!*2!) is the max number, right? if you've got 5 elements and combine two of them
120/(6*2)=10
so far:
wood, ice, blast, scorch...
what else did we have?

I think I recall something about Yin & Yang. And that might be a combination of two elements already.
