Chakra Nature Chart - Strengths & Weaknesses

All members of Naruto Ancients are expected to respect the x strong/weak against y system of the ninja world. An elemental technique of the same rank of another technique would be judged by the nature of that technique vs the nature of another technique, if the two aren't strong/weak against one another, then the two techniques would likely clash instead of one overcoming the other. Of course, there are always variables to the effectiveness of a technique versus another technique.
