You have pushed the boundaries of your Wisdom, bringing it to heights that before were impossible. You gain the following benefits:

• You increase your maximum Wisdom score by 2.
• You add half your proficiency bonus to Wisdom ability checks and saving throws that don't already add your proficiency bonus. This has no effect if you're already adding half your proficiency bonus to the roll.
• Whenever you roll an attack roll, saving throw or ability check using your Wisdom modifier, or you force a creature to roll a saving throw with your Wisdom modifier added to the DC, you may use your reaction and take one point of exhaustion to double your proficiency bonus to the roll or save DC. You can use this ability after the roll but before you know the result. If you are not adding your proficiency, or adding half your proficiency, you instead add your full proficiency bonus. If this is used for an attack roll, if the attack hits it is a crit. This ability has no effect if you are already doubling your proficiency bonus from another effect.
