This collection does not include Infernal castes.
All castes/aspects are labeled (mouse over the specific brush and the name will pop up).
To install, simply place the .abr file into your photoshop brushes folder, restart the program, and then load the brushes from the drop-down menu (or select 'Load Brushes' and find the .abr if you do not wish to put them in the brush folder).
