I'm having a blast leveling NIN to max level, but I'm still trying to get the rotation down. So far, I'm at level 40 and still have a ways to go.

But for the skill Mug, am I supposed to be using that on cooldown? The tooltip says if I used it as a killing blow, it increases the chance for the mob to drop something extra. So, that led me to believe I was supposed to be using it as a closer.

However, I feel like it's a major DPS loss if I'm not using it as part of my regular rotation. So, I was just curious on the correct way to use it.
