Gloomix

The Witches' Gloomix is a plot element in the second season, a parallel to the Winx Club's Charmix. It takes the form of a glowing necklace or wrist cuff with a single gem on the end. The Trix receive the Gloomix from Lord Darkar, and use it in a Convergence during the second half of the season. So far, the only witches to earn this are Icy, Darcy, and Stormy.
