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.
Location of Grubfather in Forgotten Crossroads
Charm Synergies
 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 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. |
Charm 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. |
 Soul Catcher |
Good for a Spell-focused build as it further increases SOUL gained throughout a battle. |
 Soul Eater |
Good for a Spell-focused build as it further increases SOUL gained throughout a battle. |
Trivia
- The amount of Mask damage taken in one hit does not impact the amount of SOUL gained, as it always grants 15 SOUL (25 with Grubberfly's Elegy).
