Mirror Spell

When you cast an arcane spell, the spell is treated as if you had cast it twice. The two copies of the spell are resolved simultaneously. They may have the same or different targets, and both copies of the spell are resolved separately. To use this feat, you must spend a spell slot as if you had used it to cast the duplicate spell. This spell slot must be of the same spell level or higher as the spell you cast.

You may channel additional arcane energy to duplicate the effects of a spell you have just cast.
