Linguist

You have studied languages and codes, gaining the following benefits:

• You gain two proficiency tiers in three languages of your choice.
• You can ably create written ciphers. Others can't decipher a code you create unless you teach them, they succeed on an Intelligence check (DL equal to your Intelligence score + your proficiency bonus), or they use magic to decipher it.
• The time investment and cost to learn a new language (from Xanathar's Guide to Everything) is reduced by half.
• When listening to a spoken language you don't understand for an hour or more, you can pick up the basic gist of what is being said.
