Auto Attack Detection + Every x Attacks

[hdm]

Something like detect auto attacks is possible ? Like Damage Detection, but only for auto attacks. And if there is this system, can I somehow do something like "Every 3 attacks the attacker is healed (or stun or whatever, just for example)" ?

This lets you turn Auto Attacks on or off, so maybe there's a way to modify this to do what you want?
