This is my favorite and most frequently used brush. Nearly all of my picture are refined with it. It effectively adds detail and texture while refining, eliminating the need for additional texture brushes. If you prefer to minimize color variation, you can check the "Color Blending" — this will blend colors while preserving a reasonable level of texture. (Note: This brush is intended for detailed refinement, so avoid setting the brush size too large, as it may cause the software to slow down.)
