The Brush Variance palette lets you customize the settings in the Tool Options palette for particular brush options. You can also make random adjustments by increasing the Jitter percentage.
You may find the most benefit to using Brush Variance palette settings if you use a pen tablet or a 4D mouse.

If you have a variance loaded with a brush and then load another brush without loading its variance, the new brush can take on the variance settings from the previous brush. Click the Reset Brush Variance palette button to clear any leftover variance settings.
You can save your modified brush as a brush tip or as a preset. For more information about saving brushes and presets, see Creating brush tips and presets.
