Grubsong

Description
Contains the gratitude of freed grubs.

Gain SOUL when taking damage.

How to Acquire
Gifted by the Grubfather after the player has freed 10 Grubs.

Usefulness
This is perhaps one of the best charms available with a one-slot cost, 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.
