So just like the Coatlnix quest a witch looking to become a Flamiarch has to obtain/craft a Coatlnix Ingot and present it to the source of Coatlnix. Unlike fairies however, witches usually work more closely with the elemental companions of each quest (in this case the Coatlni). Witches need a gift from their elemental companions to add to their uniform in order to handle the ethereal power bestowed by the elemental quests. Witches becoming Flamiarch get a djinn’s third eye. These are collected by djinn's family after a family member's death(djinn's turn to ashes when they die but their third eye solidifies into a metallic bone type material). They are considered familial heirlooms and lends a drop of Eternal Flame magic for the witch to build on. The elemental witch forms still influence the witch’s biology, so here Stormy, who has a bit of Dominian heritage in her, has some scales as a result.
