How to unlock the Clawline in Hollow Knight Silksong

How do you unlock the Silksong Clawline? You may have come across hanging rings during your journey across Pharloom, leaving you wondering what they're for. As it transpires, Hornet eventually utilizes them to trek across some of the kingdom's trickier terrains, though only after she learns the Clawline skill.
In Hollow Knight Silksong, Clawline grants Hornet the ability to throw her needle out like a harpoon, granting her a better means to close the gap with terrain and enemies alike than the standard dash. It's also a very handy tool for evading attacks from the various Silksong bosses you'll encounter throughout one of the best Metroidvanias. It won't become available until Act 2, so be sure to make a break for it as soon as you can.
