In Hollow Knight, there are a vast number of sights to see and items to collect. One of the most important things you will need throughout your journey is Charm Notches. These allow you to equip charms that can vastly change your play style. You start the game with three charm notches and there are eight more that you can unlock.
As some charms require multiple notches, you will want to seek out all of the additional notches. Having 11 notches will give you much more freedom in how you equip charms and when you need specific ones. There are a total of 45 charms in Hollow Knight so there are numerous possibilities of charm combinations. You can find all the additional charms, their locations, and unlock requirements below.
