This is a Revelation — a class feature gained through that class's own talent choices, not a feat you pick through normal feat selection.

Your phantasmagoric displays accurately model the mysteries of the night sky, dumbfounding all who behold them. Each creature affected by your illusion (pattern) spells is treated as if its total number of Hit Dice were equal to its number of Hit Dice minus your Charisma modifier (if positive).
