Enhance

"Enhance" (強化 Kyōka) is an attribute given to cards with abilities that increase the monsters' power/defense. It is currently unique to Dragon World, though this may change in the future due to it having no known connection to dragons.

Dragoenergy had it as a secondary attribute, but for some reason, it was removed on the official release of Trial Deck 1: Dominant Dragons. However, this can change in future reprints.
