Enhancement Alchemy is a skill that is used to add extra attributes to items. Unlike Refinement Alchemy, Enhancement Alchemy does not draw out true or hidden potential, but rather adds potential to something that was previously common, or adds another effect that works with previously gained effects.
Skill Encyclopedia descriptionEdit
"The user is proficient in using alchemy to give an Item an additional effect, emulating the effect of an Enhancement Seal. The result is typically a single Item that has a new effect that complements its previous effects."
