Joni's Blessing

Joni's Blessing is a Charm in Hollow Knight. It changes all masks to Lifeblood masks and increases masks by 40% (rounded up). When selecting Shell binding in the  Pantheons, it increases masks from 4 to 7 (10 with Fragile Heart/ Unbreakable Heart).

Amount of Lifeblood Masks
The 40% increase in masks granted by Joni's Blessing only takes into account the base masks and the two masks added by Fragile/ Unbreakable Heart. Masks added by Lifeblood Heart and Lifeblood Core are not included in the calculation.

Usefulness
As with Lifeblood Heart and Lifeblood Core, Joni's Blessing is more useful in a Spell-focused build where SOUL can be used to cast spells rather than heal. As such, it should be saved for later in the game when more Notches have been acquired.

How to Acquire
Found in Joni's Repose in Howling Cliffs. The charm is resting on the corpse of Blue Child Joni.

Trivia

 * Reaching 1 Mask while having this charm equipped will not create the black streaks across the screen.
 * If the Knight dies, the HUD displays a single empty mask, representing a maximum of 1 HP with a regular mask. This affects the Knight's Shade health and will render it to die in one hit.
 * There is a glitch where occasionally the Knight will gain one additional hit point after they have taken their supposed available last Lifeblood mask hit. This additional Mask is a normal white health point but will be covered in the black fog effect until destroyed.
 * The actual formula of Lifeblood masks (as in code) is: (int)((float)max_health * 1.4) + 1. For max health 5 and 10, floating point precision problem cause 5 * 1.4 = 6.999999 and 10 * 1.4 = 13.999999, resulting 7 and 14 Lifeblood masks, respectively.
