MOUNTED MASSACRE [Combat, Cavalry]

     You are a force of seemingly limitless destruction when fighting astride your mount.
Prerequisite: Great Cleave, Mounted Combat, BAB +12
Benefit: If you or your mount deal a creature enough damage to make it drop (typically by taking it to below 0 hit points or killing it), you or your mount can take an immediate extra melee attack against any other creature within reach.  If the opponent was dropped by you, the extra attack can be made with any melee weapon you wield, but using the same modifiers as the attack which dropped the opponent.  If the foe was dropped by your steed, its extra attack is of the same type and bonus as the original attack.  There is no limit to the number of times you can use this feat per round, and your steed can take a 5-foot step between each extra attack.
