Reactive Counterspell

Reactive Counterspell
Type of Feat: Spellcasting Prerequisite: Improved Counterspell, Improved Initiative Use: Automatic.

Once per round, you can counterspell an opponent's spell even if you have not readied an action to do so. This counterspell action takes the place of your next turn.

Gameplay Notes
This ability is useful to avoid being caught by surprise, or when there are multiple enemy spellcasters. The spell 'duelward' serves as a weak substitute.
