Unshakable Concentration

Your mental determination has grown to be unwavering, making you a tricky person to read while at times causing you physical strain in exchange for crucial focus. You gain the following benefits: 

• Increase your Charisma, Constitution, Intelligence, or Wisdom score by 1 to a maximum of 20. 
• When you are utilizing a Tool(Gaming Set) with which you are proficient, other creature’s attempts to contest you using Wisdom(Insight) checks are made at Disadvantage, and your attempts to contest them using Wisdom(Insight) checks are made at Advantage. 
• When you would fail a Constitution(Concentration) saving throw as a result of taking damage, you may suffer one level of exhaustion to pass the saving throw instead.
