All the items you find in the world of ELEX II are useful in some way, either as resources or equipment, or just merchandise for sale.
Below you will find a list of items that you should pay special attention to.

Elexit is the most important raw material in Magalan. Do not sell it, although it is described as "Valuables", because you will need it in Trainers do Learn Skills.
Recipes & Blueprints
Recipes & Blueprints allow you to craft and produce new items, weapons and equipment. Without them it will not be possible. Try to collect or buy the Recipes that you will use in the future, but remember that they will require the appropriate Skills during production.
Fuel
Fuel will allow you to upgrade your Jet Pack, it is limited in quantity so collect whatever you find.
Retrorockets
