Combat Reflexes (Homebrew)

You respond more quickly and repeatedly to opponents who let their defenses down.

Benefit: When foes leave themselves open, you may make a number of additional attacks of opportunity equal to your Dexterity modifier (a minimum of one extra attack) per round. For example, a fighter with a +2 dexterity modifier would be entitled to three attacks of opportunity per round - one attack that all players are entitled to plus an additional two from his +2 modifier.
