With a quick sprint, you retaliate against the caster of a spell you countered. When you successfully counter a spell, you can move up to your speed as part of the counterspell action, as long as you end your movement with the target of the counterspell within melee reach. Your movement from this ability doesn't count toward your total movement for the round. If the target's casting would have provoked an attack of opportunity, you can immediately take an attack of opportunity against the target.
