Fairy

Fairy is a buff cast by the Fairy Bell, which takes the form of a light-providing "fairy" that follows the player. It uses no mana when summoned. The Fairy is randomly colored, and may be blue, green or red. It is also faster and brighter than the orb summoned by the Shadow Orb.

Trivia

 * The fairy is a reference to Nintendo's The Legend of Zelda series. The three color fairies represent the three goddesses of the series.  Farore is green, Nayru is blue, and Din is red. The fairy that follows you in-game resembles Navi, Tatl, and Proxi from Ocarina of Time, Majora's Mask, and Hyrule Warriors respectively.
