I didn't make the animation or the behavior. They have already been there in skyrim but without the action to trigger them. That what this esp do, It allow you to do this attack when you dual power attack (hold both mouse buttons) with greatsword. I said 3rd person though it still work in 1st person but with buggy animation (you only swing with one hand in 1st person) which maybe the reason they set it aside.

  So what there beyond the cool animation?

• all 3 hits have hitframe which mean every swing register a hit.
• Power attack behavior so every hit stagger.
• You can rotate while doing the attack so you can hit multiple enemies.
• Seem like you can do it in sneak mode too, But not sure if it because some behavior mods i have installed or not.
