This feature has been removed from the game. Nano and aiding was a category of skills. It included matter metamorphosis, biological metamorphosis, psychological modifications, matter creations, time and space alteration, sensory improvement and modification, first aid, and treatment. The 18.7 patch removed the nano and aiding category. It placed matter metamorphosis, biological metamorphosis, psychological modifications, sensory improvement, time and space, and matter creations into a new nanos & casting category, and first aid and treatment into a new combat & healing category.
