Signature Metamagic (Sorcerer Revised)

Additional (11th) level feature

You have grown more in tune with twisting magic to meet your needs. Choose one of the metamagic options you know (other than Empowered Spell) and make it your Signature Metamagic. When you use your signature metamagic, you can spend 1 less sorcery point.

Whenever you reach a level in this class that grants the Ability Score Improvement feature, you can replace your Signature Metamagic whenever you level up.
