Boes are shuffling, hazy balls that take two forms: the Black Boes, which thrives in the darkness and beneath shadow, and the White Boes, which flourishes in high-intensity light and under snow-like conditions. Both types are not very threatening when isolated, and can be dispelled easily with a single sword swipe. However, these floating fiends tend to cluster in groups, and in such situations, Link may have to switch fighting tactics to deal with them accordingly.
