Origin Feat

When you take the Search or Study action, you can give yourself Advantage on any ability check made as part of that action. You can use this feature a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest. If the check fails, the use of this feature isn't expended.
