This is a hollow knight mod that adds a charm that at it's base costs 3 notches and is automatically unlocked. For each nail art you have, it will increase the cost by 1 but also increase the nail size by a good amount. With all nail arts, you even get an extra boost to the size. Really big if you combine with other nail charms. I also added a extreme mode that can be changed in the globalsettings that makes the charm cost 0 notches and grant you more nail length than the maximum length on the normal mode. Have fun. Depends on the SFCore mod, so make sure you have that.
