You can channel energy to gain an additional attack against undead in melee.
Prerequisite: Dex 21, Divine Vengeance, Extra Turning, ability to turn or rebuke creatures.
Benefit: Spend one of your turn/rebuke undead attempts to gain the ability to make one additional attack each round at your highest base attack bonus with any melee or ranged weapon. This additional attack must be directed at an undead creature. The effects of this feat last for a number of rounds equal to your Charisma modifier (with a minimum of 1 round with the extra attack).
