Just an idea, but since we have imbuements for resist for every type of magic.
Would it be possible for the game to tell you what magic is in the air when spells are cast and you are the target. Or in the vicinity.
Eg.
Don't see any downside to this, helpful for npcs.
When it comes to guilds I don't think its a big secret being revealed.
They are revealing more by using the spell in front of you.
Be it trusting you or trying to nuke you.
It could be a good idea for a permanent quest reward.
As the idea is a little similar to draconian names quest, after you complete it you see the world a little differently.
