Elementite can be found throughout your journey in Visions of Mana. Collecting Elementite from the crystals you find during your travels can restore some of your mana and give you some elemental points. Knowing all of the Elementite locations in Visions of Mana is important if you want more points.
Visions of Mana – Tourism Guide | PS5 and PS4 games
This manual is still under development and will be updated soon.
This guide will show you the location of every Elementite Crystal in Visions of Mana and what element it corresponds to. You may need to return to the map to pick up any Elementite you passed by.
Be aware that you cannot collect Elementite if you do not have the corresponding Vessel; and, from what I've noticed, they only show up on the map if you have the Vessel. I found most of these without the Vessels, and it was… a lot.
