Ritual of the Feathered Knife

Activation Cost: 50,000LP
Cost per ½ Heart of Damage: 20LP

The Ritual of the Feathered Knife searches a 31x31x41 area around the Master Ritual Stone for players. When it finds someone, it deals one damage to them and generates Life Essence in the nearest Blood Altar (in a vertical range of 14 blocks and a horizontal range of 9 blocks). Each point of damage costs 20 LP from the activator's Soul Network and generates 100 LP in the Altar. This effect respects any Runes of Self-sacrifice around the Altar.

The Ritual of the Feathered Knife will not reduce a player's health below 3 hearts by default.

Will Type Effect
Raw Increases the speed of the ritual based on the total Will in the Aura
Corrosive Uses the player’s Incense to increase the yield: for the cost of 20 LP, converts all your HP above the minimum health for sacrificing into the right amount of LP in the Altar + Bonus % if you are “Incensed”
Steadfast Sets the minimum health for sacrificing from 30% to 70% (if there is at least 10 Steadfast Will in the Aura)
Destructive Increases the yield of the ritual based on the total Will: gives a bonus between 0 and 20% depending on the quantity of Destructive Will in the Aura
Vengeful Sets the minimum health for sacrificing to 10 % (if there is at least 10 Vengeful Will in the Aura) Overridden by Steadfast for the Owner if active.

Even without Steadfast, Vengeful has no effect on the Owner. So maybe Steadfast isn’t even effective for the non-Owners.

If you’re an adept of Self-sacrifice (and if you don’t want to eat all the time), you can combine this Ritual with the Ritual of Regeneration, but without Will effects, it’ll lead to a loss of LP: it costs 20 LP to convert 1 HP into 100 LP and 100 LP to regenerate 1 HP. But with Corrosive Will and the Bonus % of the Incense Altar, you can produce a lot and even get a better yield than the Well of Suffering Automation (having Tough Palms lv10 and a lot of Runes of Self-sacrifice helps too).
