Water jutsu should get a damage boost while standing on water

[Zeller]

Water jutsu should get a damage boost while standing on water. It would make sense, and could be a cool game mechanic.
It could be 5-10%, so that instead of Water Bullet dealing 26 base damage at max level, it would deal 29. I don't know if it would be possible to implement, but I think it seems like a good idea.
