Manic Action

Every now and then, you have a burst of inspiration that allows you to take decisive action. You gain the following benefits: 

• Increase your Intelligence score by 1, to a maximum of 20. 
• Once per round, you can take one additional bonus action or reaction. Once you have used this ability three times, you must complete a long rest before you can use it again. 
• Once per round, after making an Intelligence saving throw or ability check, but before the DM announces whether the result is a success or failure, you can roll 1d4 and add the result to your roll. Once you have used this ability three times, you must complete a long rest before you can use it again.
