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)., 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 scorching ray aren't eligible, but ray of frost and chromatic orb are.
When you cast a spell that forces other creatures to make a saving throw, you can protect some of those creatures from the spell's full force. , To do so, you spend 1 sorcery point and choose a number of those creatures, up to your Charisma modifier (minimum of one creature)., A chosen creature automatically succeeds on its saving throw against the spell.
