Percussive Maintenance

You have learnt the power of fixing things by hitting them really hard. 

• When hitting a creature with an unarmed attack, it will immediately remove any charmed or frightened conditions.  
• Hitting a construct or machine that is broken with an unarmed attack will immediately repair it. 
• Hitting a book or transcript with an unarmed attack will allow the player to make a wisdom check to understand a small amount of the text that was hit. 

Inspired by the trait in the game West of Loathing.
