Another character specific trophy. In order to earn this, you must be playing as Hagoromo Gitsune. She's the girl all in black with the multiple tails behind her in the character select screen. As with the others, you can earn this in any mode other than training. This includes local versus with a second controller.
This one is a bit different from the others. In order to do this, you will have to press Up+
and hold it until the animation finishes. You'll see that your character begins to glow a pinkish purple after you do it. This tells you that she's able to absorb health with her attacks. Then, you can use any of her attacks that utilize her tails to drain health from your foe. I used Forward+
, as it deals out a few more hits. After you use your attack to drain health, you'll have to press Up+
and re-enter the draining state and repeat this process until it unlocks.
