One of the most useful (and cool-looking) abilities in Team Cherry’s Hollow Knight is the Crystal Heart ability. The Crystal Heart gives the Knight the ability to fly forward horizontally that does not stop until the Knight hits a surface. So, a super dash.
Location
The Crystal Heart ability can be found at the end of a platforming segment east of Crystal Peak. It can be obtained by interacting with the old mining golem on the east end of the room.
Traversing the Crystal Peak area would be impossible without the Mothwing Cloak (dash), Mantis Claw (clinging to walls and wall jump), and Desolate Dive (powerful dive to the ground).
To perform the Crystal Heart, hold the assigned super dash button (while the Knight is on the ground or clinging to a wall) to concentrate force. Then, release the button to fly forwards when it is fully charged. The Knight will continue to fly forward until he hits a surface, is interrupted by damage, or when you press the jump or super dash button again.
Aside from flying forwards, the Crystal Heart also damages when it contacts an enemy. It deals ten damage to enemies, and this ability will not stop the movement or damage the Knight.
Even though the Knight doesn’t have to face and fight any boss to obtain this ability, the challenge is the path leading to it. Be ready to get frustrated because of obstacles on your way to getting the Crystal Heart ability. You’ll be facing a lot of Glimbacks, Husk Miners, conveyor belts, revolving platforms above crystals that inflict damage, and crystal beetles that fire laser beams. Despite this, the Crystal Heart ability is useful and worth investing your time to obtain.
