Expanded Spell List

1st-level Frozen Bloodline feature

You learn additional spells when you reach certain levels in this class, as shown on the Clockwork 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.
