You harbor a wellspring of Profanity energy within yourself. This energy is represented by your Profanity dice, which are each a d6. You have a number of these dice equal to twice your proficiency bonus, and they fuel various profanity powers you have, which are detailed below.

Some of your powers expend the Profanity Energy die they use, as specified in a power’s description, and you can’t use a power if it requires you to use a die when your dice are all expended. You regain all your expended Psionic Energy dice when you finish a long rest.
