Eco skills are improvements upon and standalone abilities related to Jak's eco powers in The Lost Frontier. They can be unlocked, or "learned", with dark eco, dropped by and collected from fallen enemies. Jak must then go to Keira, who practices her sage abilities to help Jak receive the skills selected from a menu. Keira is most commonly available at her workshop in the Phantom Blade or in downtown Far Drop, but was also available in Aeropa for the short time you visit.
You may select from four categories: red eco, yellow eco, blue eco, and green eco. There are no dark eco or light eco powers, unlike in the game's predecessors, thus there are no corresponding skills available. Each skill in a given category is unlocked sequentially, meaning you must purchase them in order of appearance, each increasing in cost as you progress (though you can select from any of the categories as you please). Once unlocked, the skills are free to use and expend eco from neither the dark eco meter nor the eco power meter.
