Learn about water+earth combo by looking at the mud alternative release.
That is usually what is created when the two are combined, other then that you can release a wave of water and then throw in some chunks of earth. However, there is not much to actually go on. Tbvh, a water+earth combo in my opinion is useless for creating a new or unique form. It can work well with an onslaught of attacks combing water and rocks. Even then it is usually situational and not that safe to use. So, I just need to know if you have an understanding of water+earth, or aka Mud z.z.
Any questions?
