Effects

Adds fire attack power equal to 65% of the casting catalyst’s Faith-based scaling for 7 seconds. Other catalyst scaling attributes do not increase this bonus.

The burn lasts 2 seconds and removes 0.1% of the target’s current maximum HP plus 1 HP per tick, at intervals of about 0.1 seconds. This HP loss is separate from the impact’s damage and defenses. Applying the same burn again refreshes its duration without restarting its tick clock. The number of applications depends on actual hits; maximum-HP restriction is a separate effect.

Technical details

Fire Attack Power

Adds 65% of the catalyst's Faith-based scaling as fire damage to the right-hand weapon. Other scaling attributes on a hybrid catalyst do not increase this enchantment. Lasts 7 seconds. Applies only to the selected weapon or shield. It does not add damage or protection to your other hand. Old Lord's Talisman extends this spell buff while it remains equipped.

Health Points

The burn lasts 2 seconds and removes 0.1% of the target's current maximum HP plus 1 HP on each native tick. This is direct HP loss, separate from the impact's defense and elemental damage calculation. Applying the same native burn again refreshes its lifetime while preserving its existing tick clock. Different native burn identities remain separate. The engine uses the supplied actual update deltas, checks for a due tick before advancing its clock and combines burns due on the same update before integer truncation. Supply confirmed effect applications, the affected target, its maximum HP and its HP-damage suppression state. This does not infer how many projectiles or weapon hits connect. Maximum-HP restriction is a separate effect.

In-game description

A black flame incantation of the Godskin Apostles.

Engulfs armament held in the right hand with black flame.

This incantation can be cast without delay after performing another action.

Black flame is weighty. After dealing damage it continues to sap foes' HP for a very short time.

Where to find

Stormveil Castle courtyard cellar, then Church of Vows

Limgrave

Starting Site of Grace: Liftside Chamber

Before you go

Bring one Stonesword Key.
Bring 6,000 runes to buy the unlocked spell.

Follow Stormveil's side route to the large courtyard filled with soldiers, then activate Liftside Chamber so you have a nearby return point.
From the courtyard, search its southern side for the stairs into the cellar. If you entered through the main gate, this entrance is on your left.
Go down and clear the rats before using the imp statue beside the fog barrier.
Spend one Stonesword Key to open the room. Open both chests inside; one holds Godskin Prayerbook and the other holds the Godslayer's Seal.
Go to the Church of Vows on the raised ground in eastern Liurnia, northeast of Raya Lucaria Academy. From the Artist's Shack in Liurnia, follow the road north and take the uphill branch toward the ruined church.
Speak to Miriel, the enormous turtle wearing a white mitre inside the church.
Give Miriel the Godskin Prayerbook, then buy Black Flame Blade for 6,000 runes. The seal from the second cellar chest does not teach either spell.
Corhyn can also teach the book if he is still available. Miriel stays at Church of Vows, making him a convenient choice when Corhyn has moved during his quest.

Notes

Cast this with a sacred seal. You need 17 Faith.
It takes 1 memory slot and uses 15 FP to start casting.
Equip the sacred seal in your left hand and the weapon you want to buff in your right. The weapon and its current affinity must allow weapon enchantments; changing to an incompatible affinity or weapon can prevent the cast.
The buff is brief. Apply it immediately before your attack sequence rather than at the start of a long approach.
The coating lasts 7 seconds. Old Lord's Talisman extends it to 9.1 seconds, which is still short enough to apply immediately before an opening.
Casting after a roll, jump or attack, or while sprinting, uses its faster application. Use that quick cast as you move into range rather than spending the short buff on a long approach.
Adds Fire attack power equal to 65% of the seal's Faith-based casting scaling. Arcane or Intelligence contributions on a hybrid seal do not improve this weapon enchantment.
Weapon hits also apply a 2-second black-flame health drain. The damage depends partly on the target's maximum HP; the drain is separate from the extra Fire attack power.
Repeated hits refresh the drain. Fast attacks help keep it active, but do not create an unlimited stack of separate full burns on one enemy.
Godslayer's Seal does not add its black-flame school bonus to this coating. Faith-based casting scaling matters for the added Fire damage, while upgrading the seal does not increase the drain's percentage.
It occupies the weapon-buff slot and replaces incompatible grease or another weapon enchantment. Standard, Heavy, Keen and Quality usually permit it; elemental and status affinities generally do not.
The coating applies through eligible weapon contacts. Do not assume a separate ranged skill projectile carries its health drain simply because the weapon is coated.
Costs 6,000 runes after handing Godskin Prayerbook to Corhyn or Miriel. The book does not provide a free spell or make an incompatible weapon buffable.
