Metamagic. The spellcaster has 12 sorcerery points to use on the following Metamagics

Quickened Spell. When you cast a spell that has a casting time of 1 action, you can spend 2 sorcery points to change the casting time to 1 bonus action for this casting.

Twinned Spell. When you cast a spell that targets only one creature and doesn’t have a range of self, you can spend a number of sorcery points equal to the spell’s level to target a second creature in range with the same spell (1 sorcery point if the spell is a cantrip).

Subtle Spell. When you cast a spell, you can spend 1 sorcery point to cast it without any somatic or verbal components.

Draconic Resilience. As magic flows through your body, it causes physical traits of your dragon ancestors to emerge. Parts of your skin are covered by a thin sheen of dragon-like scales. When you aren’t wearing armor, your AC equals 13 + your Dexterity modifier.

Elemental Affinity. When you cast a spell that deals damage of the type associated with your draconic ancestry (Fire), you can add your Charisma modifier to one damage roll of that spell.
