Shell binding in the Pantheons, it increases masks from 4 to 7 (10 with Fragile Heart/
Unbreakable Heart).
Amount 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/ 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.
Charm Interactions
 | Hiveblood (In all other cases, Hiveblood does not affect Lifeblood masks.) |
 | Fury of the Fallen Lifeblood masks from Joni's Blessing are not treated like normal lifeblood masks, and instead are treated like actual masks. Due to this, Fury of the Fallen will only trigger when the Knight has one mask remaining. |
 | Grubberfly's Elegy Lifeblood masks from Joni's Blessing are not treated like normal lifeblood masks, and instead are treated like actual masks. This makes Grubberfly's Elegy only trigger when the Knight is at the maximum amount of masks. |
 | Fragile Heart Joni's Blessing will include the Masks given by Fragile/Unbreakable Heart when calculating its hp 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. |
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.
