Siren's Magic

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

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 enchantment, illusion or a transmutation spell from the sorcerer, warlock, or bard spell list.
