You did not always possess arcane gifts within. These abilities were gained through contagious, communicable means. Perhaps a disease that escaped from a plane of high magic, or a parasite gifting you with magical prowess. However infected, these sorcerers are so fundamentally altered by an arcane pathogen that it infuses their blood with the essence of the arcane weave. While this infection is considered to be a gift by some, others believe it to be a curse to possess such abilities. Nations have been known to try to deliberately eliminate those infected by such pathogens, for fear of the common masses gaining powerful arcane abilities. Abilities they may not be able to control.

Disease Magic

1st-level Arcane Infection Soul feature

You learn additional spells when you reach certain levels in this class, as shown on the Disease Spells table. Each of these spells counts as a sorcerer spell for you, but it doesn’t count against the number of sorcerer spells you know.

Whenever you gain a sorcerer level, you can replace one spell you gained from this feature with another spell of the same level. The new spell must be an abjuration or a transmutation spell from the sorcerer, warlock, or wizard spell list.

This creature is infected by this spell until they take a short or long rest.
