You awaken to your psionic potential, which enhances your mind or body. Increase one ability score of your choice by 1, to a maximum of 20, to represent this enhancement. You also harbor a wellspring of psionic power within yourself, an energy that ebbs and flows as you channel it in various ways. This power is represented by your Psionic Talent die, the size of which is a d6. You can use your Psionic Talent die in the following ways:

• When you make an ability check with the ability increased by this feat, you can roll your Psionic Talent die and add the number rolled to the check. You can choose to do so before or after rolling the d20, but before you know whether the check succeeded or failed. You can’t use this feature again until you finish a long rest.
• Once on each of your turns when you hit with an attack roll that uses the ability increased by this feat, you can roll your Psionic Talent die after you make the damage roll and then replace one of the damage dice with the number rolled on the Psionic Talent die. You can’t use this feature again until you finish a long rest.
