Purple Crystals (Japanese: パープルクリスタルPurple Crystal) are monsters found late in the game within The Sky Scraper. They tend to appear with their own kind, or with other enemies, such as Crystals. They seem to be strong against magic, but weak to physical attacks.
When defeated, Purple Crystals will relinquish two Mii eyes and a mouth.
These monsters look like large, pinkish-purple snowflakes with a glass-like sheen to them. There's two Mii eyes and a mouth in the center of the snowflake, forming its face.
