Counterstrike Bracers

Each of these steel bracers bears the image of a stacked pair of daggers pointed in opposite directions.

Counterstrike bracers allow you to answer an unsuccessful melee attack against you with an unexpected riposte. You can activate the bracers immediately after an enemy has missed you with a melee attack. Doing this grants you a free attack of opportunity against that enemy (even if you have already used up your allotted attacks of opportunity for the round). You must activate the bracers before your enemy takes any other attacks or actions.

This ability functions two times per day.
