Joni's Blessing

From Hollow Knight Wiki
Jump to navigation Jump to search

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 the Godmaster content Shell binding in the Godmaster content Pantheons, it increases Masks from 4 to 7 (10 with Fragile Heart/Grimm Troupe content Unbreakable Heart).

Number of Lifeblood Masks

Masks Lifeblood Masks
5 7
6 9
7 10
8 12
9 13
10 14
11 16

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


When having Joni's Blessing equipped it becomes easier to enter the Lifeblood Chamber in the Abyss. With 8-9 Masks and Fragile Heart/Grimm Troupe content Unbreakable Heart or Lifeblood Heart, it is easy to make the 15-Mask threshold, thus earning Lifeblood Core.

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, but Lifeblood Core remains inaccessible.

However, Lifeblood Core is usually a more efficient Charm for adding survivability in the endgame. Joni's Blessing adds at most 5 Lifeblood Masks while Lifeblood Core adds 4, costs 1 less Notch, and does not prevent healing.

How to Acquire

Found in Joni's Repose in the Howling Cliffs. The Charm is resting on the corpse of Blue Child Joni.

Charm Synergies

Hiveblood can regenerate Lifeblood Masks granted directly by Joni's Blessing, though it takes twice as long (20 seconds). Also changes the visuals of the Knight's Masks.

Charm Combo Tips

Fragile Heart
Joni's Blessing includes the Masks given by Fragile/Grimm Troupe content Unbreakable Heart when calculating its Mask bonus.

Lifeblood Heart
Stacks with both Lifeblood Heart and Lifeblood Core.

Lifeblood Core
Stacks with both Lifeblood Heart and Lifeblood Core.

Shaman Stone
Since Shaman Stone is used in Spell-casting-focused builds, it is good to combine it with Joni's Blessing in battles where healing is difficult or impossible.



  • Reaching 1 Mask while having this Charm equipped does not create black streaks across the screen.
  • If the Knight dies, the HUD displays a single empty Mask, representing a maximum of 1 regular Mask. This affects the Knight's Shade health and causes it to die in one hit.
    • There is a glitch where the Knight occasionally gains one additional Mask after they have taken damage to what is supposedly their last available Lifeblood Mask. This additional Mask is a normal white Mask but is 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.
  • When using the Grubberfly's Elegy Charm with Joni's Blessing, the Nail projectiles stop firing after taking any damage. Regenerating Masks with Hiveblood does not re-enable the projectiles.
