A feat to counter criticals

[Postie]

I've been mentally toying with the idea for this feat for a while and can't get it right.

Name: Massive retaliation ?(general)

prerequisits: Iron will , attack bonus +3?

Effect.. If you recieve an attack that is a confirmed critical you can make an immediate responding attack out of initiative sequence that generates Aoa's (which may hit opponent as per bullrush) adding your wisdom mod , or your Charisma mod ( I haven't decided) to normal damage calculation's i.e. strength etc.
Being at -1 to -10 hit points does not prevent this attack.

I have this vision from the movie "Excalibur" of Arthur clawing his way down mordred's spear to stab him.

I have a Negate Critical feat on my D&D page that lets you ignore a certain no. of crits per round.

A suggested rename to Riposte perhaps?

As for what it does ...

I would go with simply an AOO available at the attacker (following all rules for AOO). This represents the fact that the attacker went all out to drive the hit home etc.

There's a feat that does this in one of the Dragons Magazines.

Or you can make it a fort save vs critical damage done plus add your level to the save. Makes it rare but possible for higher level characters perhaps? This way EVERYONE has a chance of taking down their attacker if the roll is right
