Mirrored Spell (Metamagic)

An additional metamagic option for sorcerers.

When a creature you can see within 60 feet of you casts a spell, you may spend a sorcery point and use your reaction to hold that spell in mind for a short time. Until the end of your next turn you may spend an additional sorcery point to cast it as if it is a spell you know.

You must cast the mirrored spell at the level it was originally cast at. If you have no spell slots of a sufficient level to cast the spell, the spell fails.
