Knowledge from a Past Life

You temporarily remember glimpses of the past, perhaps faded memories from ages ago or a previous life. When you make an ability check that uses a skill, you can roll a d6 immediately after seeing the number on the d20 and add the number on the d6 to the check. 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.
