Abilities
Fai for starters is able easily detect magic, so if anyone has a magical ability he is able to pick up on it. Though I am sure he will not know what type of magic it is exactly, he still can sense the magic as proven when he sensed where a fake wall was because there was someone with magic ability behind it.
Not only can he detect magic, but he can use protection spells and any spells that harm people, this had been noted in a flashback when Fai mentioned the fact that any spell that was to help would always vanish from his mind once he learned it, but any spells that harmed people he would still always remember.
Fai is a pretty powerful mage since his grade D in Celes meant he was the highest ranked mage from here he was from. Also the magic comes from his eyes, the left one increases in power the more it is uses while the right one decreases. He gave the right eye magic up in Nihon, but has since got his left one back, thus his magic returned.
