Sure, a lot, if not all, of Free's powerful magic comes from the eye. His whole body (or at least the magic he's summoning gets limned in green (the color of his soul, perhaps tainted by the eye, which also appears directly on his soul), and the crest on the eye enlarges and it starts sparking.
But in episode 15, Free also uses ice magic, with or without incantation (much like Medusa and frog-girl do). No reaction from the eye at all.
