From Eco - English Wiki

Specialties are categories of skills in Eco that are discovered using research.

Players may learn specialties - and gain access to the specialty's skill tree - by spending skill points.

With each specialty learned, the cost of learning the next specialty increases exponentially. Skill costs increase from 0, 0, 5, 15, 50, 100, 300, 500 at the default multiplayer rate.

In the game skills window, specialties are categorized by professions.
