Mirror Flame Rite

You may use Smoke Mirror Way / Mirror Flame Rite plus any stored elemental energy to Nullify a spell. If you defeat the spell, you may also reflect the spell back on the spellcaster, adding any excess wager to the spell's power.

Adept

You may change the spell's modifiers (including whether it's Greater or Lesser) and choose a target other than the original spellcaster.  

Master

You may change the spell that has been cast to any other spell the spellcaster knows. The spellcaster is no longer able to cast that spell for the duration of combat.
