Raise your Intelligence attribute by 1, up to the attribute cap of 20.
Select three languages and gain the ability to read, write, and speak them.
By spending an hour, you can develop a cipher that you are able to teach to others. Anyone who knows the cipher can encode and read hidden messages made with it; the apparent text must be at least four times longer than the hidden message. Other creatures can detect the presence of the cipher if they spend a minute examining it and succeed on an Investigation check against a DC equal to 8 + your proficiency bonus + your Intelligence modifier. If the check succeeds by 5 or more, they can read the hidden message.
