Truth be told, I'm not entirely sure. I've just recently learned this branch of magic. [ thanks Portland. ] But I can detect when a spell is active. It works best if I know the spellcaster or the origin of magic.

Thankfully, there really haven't been that many opportunities for someone to curse you in the first place so it limits our options. I've been around the Summer Fae long enough both here and in Portland that I should be able to recognize if it's that strain of magic--I'm much less adept at recognizing Winter Court, however.

[ because of COURSE it's fae magic that's causing Taako to have weird dreams, what else would it be? ]
