Astrid powers up and becomes immune to all damage for 2 seconds. After 1.5 seconds, she swings her sword, dealing x (+x) physical damage. For every 2% of her own maximum HP that Astrid has lost, she will deal 1% more damage. The ability also slows the enemy's movement speed by 50% for 1.5 seconds. If the enemy's HP is higher than Astrid's, then the ability also stuns the enemy for 1 second.
