Crystal Heart is an extraordinary Ability found in Hollow Knight. It enables the player to dash forward in mid-air without colliding into the ground or any enemy. It can be activated by holding the super dash key when on the ground.
When using the Crystal Heart, you can increase your movement speed dramatically and you can even move faster than enemies if you can manage the jump. To perform the hop, simply press the shift button while in mid-air to change your horizontal position. In this way, you can increase your speed and move faster. If you can successfully hit an enemy with the crystal heart, you will have to destroy at least three enemy units before you can reach the exit platform. You can destroy the units which attack you first, but if you are facing an enemy wave, you must first clear it so that you can take out the supports.
The best strategy in using the crystal heart is to use it as part of the defense rather than an offensive tool. You can use the crystal heart to deflect missiles which fly towards you from your enemies. You can also use the defensive abilities while jumping to reduce the damage taken. Using defensive abilities can help you reduce damage taken and can allow you to stay out of harm’s way for longer periods of time.
The Crystal Heart is one of the most powerful relics discovered by the World Tree in the bygone era. It belongs to the ancient class of mysterious organization called the Order of the Stone. The reason why the crystal heart is so powerful is that it contains seven powerful relics which have the ability to turn one’s weaknesses to their strengths.
The first area where you can use the crystal heart is at the bottom portion of the map where you find the first item called the Hoplink. The Hoplink will allow you to activate the crystals located around the map. When you activate these crystals, they will fly left or right depending on where you are standing. If you are standing still, you will be able to see a circle that represents the location of the crystal heart. Once you activate the crystal heart you will be able to hop right or left to increase your movement range.
The second area in which you can use the crystal heart is at the bottom part of the map in the next area called the Eclipse. The second enemy you encounter here is the Spider Queen. Focus on destroying the spiders as you slowly make your way up to the exit that leads to the boss room. The spider queen has two forms which you can go through depending on your preference. Either her left or right side can attack you so be sure to use the focus charm here.
The third area where you can get the crystal heart is in the large circular room in the very top of the map called the Valley of Omens. The third enemy you face here is the Laser beetle. Focus on destroying the laser beetles rapidly as they come straight at you. After dealing with the laser beetles proceed to the bottom of the map where a panel with three eggs will be triggered. Use the eggs to jump to the very top of the map where a chest will be triggered and a crystal heart will drop down giving you access to the final area known as the Hall of Souls.
The last area in which you can acquire the crystal is in the room called the Hall of Souls. There is a group of three enemies that will continuously shoot lasers at you. Focus on destroying all of them including the leader while making your way to the finish line. Use the focus charm to deflect all the incoming lasers and then use a wall-jump to reach the final area in which is a boss fight against a laser collector that continually fires lasers at you that you cannot afford to miss.
