You were not born with magical abilities, but a deep,
profound anger. Perhaps you've carried it like armor
on your skin or hidden it from the world, silent and
seething. Pledging yourself to the Chained Goddess
has unleashed the burden of your rage, giving you
access to a deep magical well of anger within. You innately understand and can speak Infernal and
Celestial. Additionally, when making Charisma checks
with fiendish entities, you have advantage.
