Can you discover what tradition monk belongs to? And sorcerer?

[Fedorchik1536]

So when monks gets his first Ki Spell he decides to what tradition he belongs - either occult or divine.
Can anyone by observing monk decide which tradition he belongs to?

On other hand, Sorcerer does the same at lvl 1. Can you detect which tradition he belongs to if you only uses multi-traditional spells?

[Garretmander]

Recognize spell if it's the same tradition you're trained in.

Possibly a recall knowledge action if you're trained in the appropriate skill and have seen them casting. I think that one is up to the GM though.

For the sorceror if they ever a bloodline/focus spell that triggers blood magic, that's probably somewhere between 'obvious' and 'easy level 1' recall knowledge

How do you even tell it's a monk or sorceror in the first place?

Any unarmed fighter in a gi who talks in taoisms is going to look like a monk to your average person. Anyone in cloth who points and mumbles is the same unless you see them preparing.

You need to see a unique power for that class, and ID it with an in-game mechanism, and trust they don't have an archetype or dual-class.

Every angry fighter in a bare shirt looks like a barbarian, and Razmir has a whole nation convinced he's a god not a wizard, so whatever.
