I am trying to make my Monk character on the site and i am not seeing the Stealth Proficency for the Monk. I have the book and it deffinetly says stealth.

Check if the race or the background give you the Stealth proficiency.

The Monk class does. In the Player's Handbook it says Stealth as a proficency option.

As I said, check if the race or the background give you the Stealth proficiency. Because if either does, you already have the Proficiency in Stealth, and, therefore, Stealth is taken away from the skill options for the class.

I see what you are saying. Yes, it appears that Stealth has already been selected.
