An Ability Type groups related abilities together — "Spells," "Feats," "Racial Abilities." Create one with the green "New Ability Type" button. Give it a Name, optionally file it into an Ability Type Folder, and (Game Masters) set Secret? to hide it from players, or Private? to show it only to the owning player and GMs.

The admin sidebar organizes types into folders (All Ability Types, Unsorted Ability Types, and named folders managed via "Manage Folders") and lists Ability Type Tags for filtering. Types and the abilities within them can be dragged to reorder.
