Omniglot

You have unlocked an uncanny understanding of language, be it verbal, musical, or physical. You know the spell Tongues and have a number of Omniglot Points equal to your Proficiency Bonus. You can spend Omniglot Points on the following benefits.

• Expert Communicator. You gain advantage on CHA (Deception), CHA (Performance), or WIS (Insight) checks for the next 10 minutes(no action).
• You can cast Tongues without the need for components or expending a spell slot.
• Perceptive Fighter. If a creature you can see attacks you, you can use your reaction to force them to make the attack roll with disadvantage.

You regain your expended Omniglot Points when you finish a Long Rest.
