Imbuing/1/en
From Crea Wiki
Imbuing is the process of enhancing items. As you progress through the world some events are triggered which unlock Remna, which is a mysterious energy source that can be used to enhance items. This process of imbuing materials is quite simple. Drop remna into one slot, the material into another and you’re off! The two sources move inwards to the center and once they reach it the two items are converted into a higher quality material. For example, lumber imbued with remna creates refined lumber.
