(Do forgive me if this doesnt make 100% sense its been awhile since ive made a thread 
The question im wondering is:
1. Are there ANY elements in naruto (Chakra Natures) that CANNOT be fused/mixed together to form a new Element/Chakra Nature or jutsu?
2. are there any example in the manga that say which chakra natures CANT be mixed?
it interests me because there are strengths and weaknesses for certain Chakra nature match ups and on the other hand there are chakra nature match ups that can be combined together to form a stronger jutsu or chakra nature altogether...but when is there a point where you CANT mix chakra natures?
IS there any limitations to what elements/chakra natures that can be made?
Please, if you have any proof/ evidence to support your claim...provide the manga page for us to see!
