Storyteller Metamagic (Level 10)

Storytellers learn to harness the innate magic of tales and legends:

• You learn two Metamagic options of your choice from the Sorcerer class. You add these to your learned Metamagic Options, and these can either be used on another creatures spell as a reaction as part of the Storyteller Artificer subclass, or added to your spells as part of the Sorcerers class, the Metamagic Adept feat, or other ability you have that would do such.
• Whenever you reach a level that grants the Ability Score Improvement feature, you can replace one of these Metamagic options with another one from the sorcerer class.
