Please help sculpting tools have no concave effects

My original subdivided object cant be impacted in a concave manner. I think dyntopo added clay for every edit so far but any edit to shrink part of or push my clay inward wont work. It only will deepen down to the original size of my sphere. Its like i have a metal sphere covered in clay but id like my whole sphere made of clay. Whats going on?

I guess i could add clay all around my shere and start over but thats not conveinent and also that tool does seem very strong even with strength all the way up. (Side issue though)
