How to Breed Glowl

Glowl’s Dawn of Fire Description
A Glowl nestling isn’t afraid of the dark, it glows! The tail feathers are so intensely pigmented they continue to be luminous even when shed. Glowl plumes are highly prized as torches, and since these creatures molt only once in a lifetime, very rare.
Glow can be bought in the Monsters menu for 120 Gems.
