Is the DC on the Linguist Feat too low?

Question

I am talking specifically about the DC to create a cipher. As written the DC is INT+Proficency. This means that as a level 14 wizard with a 20 INT, I can create a cipher with a DC of 10. This seems to be quite low to me?

Have I missed something here?

Answer 1

DC equal to your Intelligence score + your proficiency bonus

This uses your intelligence score, not your intelligence modifier. Therefore the DC is 25 (20 Int + 5 Proficiency modifier).

Answer 2

You are reading INT+Proficiency as meaning INT Modifier+Proficiency.

Add the full intelligence score, so a level 14 wizard with a 20 Int, sets the DC of their ciphers as 25.
