Joni's Blessing

Joni's Blessing
Blessed by Joni, the kindly heretic. Transfigures vital fluids into blue lifeblood. The bearer will have a healthier shell and can take more damage, but they will not be able to heal themselves by focusing SOUL.
Effect	Increase HP by 40% (rounded up), all masks become Lifeblood Causes Lifeseeds to flock to the Knight instead of running away
Notch Cost

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

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

When having Joni's Blessing equipped it becomes easier to enter the Lifeblood Core room in the Abyss. With 8-9 masks and Fragile Heart/ Unbreakable Heart or Lifeblood Heart, it is easy to make the 15-mask threshold, 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 than Joni's Blessing; 4 Lifeblood masks are gained with either charm (going from 9 to 13 masks), but Lifeblood Core only costs 3 notches and does not prevent healing.

How to Acquire

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

Charm Interactions and Combo Tips

	Hiveblood Hiveblood can regenerate Lifeblood masks granted by Joni's Blessing, though it takes twice as long (24 seconds). (Hiveblood does not affect Lifeblood masks not directly gained through Joni's Blessing.)
	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 Core and Joni's Blessing.
	Lifeblood Core Stacks with both Lifeblood Heart and Joni's Blessing.
	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.
