Epic Counterspell

Epic Counterspell
Type of Feat: Spellcasting Prerequisite: Reactive Counterspell, Improved Iniative, 30 ranks in Spellcraft Use: Automatic.

Any number of times per round, you can counterspell an opponent's spell even if you have not readied an action to do so. Such a counterspell doesn't count against your later actions for the round.

Gameplay Notes
This feat removes the limit of 1 counter spell action each round. You may now counter any number of spells cast against you in the same round. You still need to have sufficient spells to counter with, however. Its most significant aspect is that you can counter while attacking or casting spells, which you cannot do wihtout this feat.
