Found the explanation for metal on youtube

"metal-atts are known for their need for control. they are organized, capable, and highly ambitious, making them very suited for leadership roles. These self-reliant attuned are not easily swayed from their goals, leading others to view them as stubborn and at times selfish. Metal-atts are prone to jealousy, so you must take care not to compare yourself to others during your magickal studies"

The short version for fire:

[they] are most known for their passion and fierceness. pay special attention to the swing of your emotions when practicing magick"
