Whenever you finish a long rest, you can replace any metamagic option you know with another metamagic option.

 

Metamagic

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). If the spell requires concentration, you have disadvantage on Constitution saving throws to maintain concentration on this spell for the duration.

To be eligible, a spell must be incapable of targeting more than one creature at the spell’s current level. For example, magic missile and fireball aren’t eligible, but ray of frost and dragon’s breath are.
