Human Aptitude

Due to a relative short life span, you have become more resourceful and competitive than other races. You often succeed when others do not.

Prerequisite: Human.

Benefit: When you make an attack roll, saving throw, or ability check but before the outcome is determined, you can roll a d8 and add the result to the previous roll.

Once you use this feature, you cannot use it again until you finish a long rest.
