You learn additional spells when you reach certain levels in this class. 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 a transmutation or an enchantment spell from the sorcerer, warlock, or wizard spell list.

Wild Magic Spells

Wild Sorcery

6th-level Wild Magic feature

When you cast any spell of 1st level or higher from your Wild Magic Spells feature, you can cast it by expending a spell slot as normal or by spending a number of sorcery points equal to the spell’s level. If you cast the spell using sorcery points and if the spell has a casting time of 1 action, you may change the casting time to 1 bonus action for that casting.
