Fay

Fay (フェイ) is a character in the BOFURI series.

Description
Fay is a spirit (精霊) in the form of a white light with wings. Depending on the terrain and the owner's magic, Fay's color and abilities change.

While in a forest or jungle terrain, Fay changed to have leaves from the surrounding trees as wings. After Iz crushed a blue crystal and causing water to flow out, Fay changed to have a body resembling a liquid. Other forms not listed were caused by crushing the following crystals; ice crystal, thunder crystal, earth crystal, fire crystal. During the explosion, several other damage types are listed and imply Iz has many other crystals not mentioned.

Companions Arc
Once enough information was out, Iz chose to pick up a fairy as a pet. She went to the old man and started the quest, The Three Trials. The materials required to create the items for the quest were scattered throughout the layer, some acquired through gathering skills and others through fighting powerful bosses. Realizing how difficult it might be, she looked to Maple for help. As Maple was stuck between her promise to Mii and her fellow guild member, Mii recognized the locations would have powerful monsters and decided to help with the material gathering. After turning the items in, Iz acquired a spirit and named it Fay.

Eighth Event Arc
After Iz promised Maple she would be in the top ranking, she showed her true strength with Fay by her side. Because a spirit's abilities change depending on the terrain and the owner magic, Iz used countless crystal to replicated magic element attacks, changing Fay's type and skill set repeatedly. As spirits have synergy with items, they can boost their effects in many ways. Exploiting this, Iz and Fay destroyed the jungle area of the event. Even Chrome was under the impression he wouldn't survive it.

Unique Combinations

 * owner's various crystals + owner's bombs + Recycle + various form skills : After making the best bombs with her crafter skills, Iz further strengthened them before repeatedly changing Fay's form and adding effects through crystals. These bombs were then set off with the crystal-string combination multiple times as [Recycle] had a chance to make them as unused. The buffs from Fay were retained.
 * owner's yellow crystal + String Water : The yellow crystal creates an electric charge that is sent through the strung water trail to ignite Iz's bombs.
