Silk

Silk is Hornet's source of energy in Hollow Knight: Silksong, and is similar to SOUL which the Knight uses in Hollow Knight.

In-game Silk is represented on the HUD by a bar with several notches.

Hornet can strike enemies with her Needle, causing them to drop Silk fibers that she then collects to use with her abilities. Each time she strikes an enemy, Hornet gains 1-2 notches of Silk.

She can use Silk to Bind, instantly healing one Mask of damage for each set of 4 notches of Silk.

Hornet can also use 2 notches of Silk to grapple onto a piece of the environment or onto an enemy, travelling to them and damaging them as well. Hitting an enemy with this ability restores 1-2 notches of Silk.

Hornet also has the ability to use her Gossamer storm. she will produce 1-3 thick, strand of threads and all will lash out around her. Can be used when airborne. This skill takes 5 bars of silk. Similar to the
