Ssun's Staff WTF?!

I've checked the sell forum and found Ssun's staff for sale. I was really surprised to see the dude's staff is a rit staff (no error possible: he posted a pic). I got one yesterday before the boss update: when I fought Ssun, he was a monk boss and I got a (very good actually) divine favor staff. Does anyone know what's going on? Has the dude been replaced by a rit boss yesterday? Or does he drop both rit and monk stuff?

I really would like to know whether I have what's now an uber rare collector or not

Ssun is a monk boss.

Ssyn is a ritualist boss.

Are you getting the two confused or did the person mistype it?

Aaah yeah indeed there was a confusion - sorry about that. Are there also Ssan, Ssen ans Sson bosses or were they more imaginative for the name of the other bosses?

Sorry for this useless topic - I cant delete it apparently.
