Grubsong is a Charm in Hollow Knight. It causes the Knight to gain 15 SOUL when taking damage.
Usefulness
A useful charm at the cost of only one notch as it provides a good amount of SOUL meter to use as healing in compensation for taking damage. The SOUL provided per hit is not enough for a heal on its own but combined with the SOUL gathered by striking enemies, or with other charms that help gather SOUL faster, this charm becomes incredibly useful for a Spell-focused build.
It also shines in difficult platforming areas where enemies are not readily available for gathering SOUL.
How to Acquire
Gifted by the Grubfather after 10 Grubs have been freed.
Charm Interactions and Combo Tips
Hiveblood In combination with Hiveblood it allows for regenerating SOUL infinitely, albeit slowly, by jumping into hazards or enemies, retreating, waiting for health to regenerate, then repeating. | |
Deep Focus Combined with Deep Focus or Hiveblood, it greatly helps to tackle difficult platforming challenges, especially the White Palace. | |
Grubberfly's Elegy When used in combination with Grubberfly's Elegy, the amount of SOUL received from taking damage is increased by 10 (to 25). | |
Weaversong When used in combination with Weaversong, the Weaverlings will collect 3 SOUL upon striking an enemy, and can even gather SOUL from enemies that normally would give none from Nail hits (such as Siblings or the Collector). SOUL can be collected even after death, before the screen transition, allowing the Knight to wake up on a Bench with SOUL. |
Trivia
- The amount of mask damage taken in one hit will not impact the amount of SOUL gained, as it will always grant 15 SOUL (25 with Grubberfly's Elegy).
