Bats Blood Ink is a formula that is tied to European grimoires, much like Doves Blood Ink, and the

Black Cat Bone. The magician or exorcist is to take a bat, and pierce it under the left wing, allowing the blood to drain out to make an ink which is exceptional for making pacts in the exorcist's Liber Spiritus, or Black Book. From The Key of Solomon The King:
TAKE a living Bat and exorcise it thus:
CAMIACH, EOMIAHE, EMIAL, MACBAL, EMOII, ZAZEAN, MAIPHIAT, ZACRATH,TENDAC, VULAMAHI; by these Most Holy Names, and the other Names of Angels which are written in the Book ASSAMAIAN, I conjure thee O Bat that thou assist me in this operation, by God the True, God the Holy, the God Who hath created thee, and by Adam, Who hath imposed thy true name upon thee and upon all other animated beings.
After this, take the Needle or other convenient Instrument of Art, as will be said later on, and pierce the bat in the vein which is in the right wing; and collect the blood in a small vessel over the which thou shalt say:--
Almighty ADONAI, ARATHRON, ASHAI, ELOHIM, ELOHI, ELION, ASHER EHEIEH, SHADDAI, O God the Lord, immaculate, immutable, EMANUEL, MESSIACH, YOD, HE, VAU, HE, be my aid, so that this blood may have power and efficacy in all wherein I shall wish, and in all that I shall demand.
Perfume it and keep it for use.
The blood of other winged animals may be taken in the same manner, with the proper solemnities.
And the note from McGregor Mathors, who translated and added editorial notes to this operation:
Note by Editor.--I cannot too strongly impress on the readers of this volume that the use of blood is more or less connected with Black Magic and that it should be avoided as much as possible.
Through adaptation, Bats Blood Ink by many occult manufacturers has been rendered to synthetic or plant-based inks which contain no bat, but are instead oftentimes dragonsblood resin. While these inks can produce results, It is in my opinion to try to sell inks which are honest- therefore I have labored to create an ink which takes the best of these inks prior: Animal, mineral, and botanical, and have created an ink that does include a small amount of powdered bat in it- which has been processed to keep the blood, but dispell any contaminants.
Genuine Bats Blood Ink (and its Spells & Workings) is a formula typically used for crossing, cursing, jinxing and hexing. At its simplest, it can be used to write a petition on a piece of paper, or photo of an enemy. “[NAME] is cursed,” written nine times on the back of a photo can be effective. To cross up a pair of lovers or a group of people, take a photo of the group, and write their names on the back of the photo in Bats Blood Ink “[NAME OF EACH PERSON] be cursed” or “[NAME OF COUPLE] separate”. This can be enhanced with Crossing Oil, Cut And Clear Oil, or a combination of the two.
Writing petitions and name papers in Bats Blood ink can be used for cursing, but it is also sometimes used to sign contracts, or seal pacts, either with Witches, Sorcerers, or Spirits. Writing a spirit’s sigil in a black book or magic book to put them inside is something that harkens back to older Liber Spiritus or spirit books.
A Simple Crossing
Take a photo of a person, and write their name on the back of it. Anoint the four corners and
center of the photo with Crossing Oil, and with Bat's Blood Ink, draw an X over the person's face in the photo. With a black candle anointed in Crossing Oil, burn the photo to ash. You can discard the ash, or to amplify the working, mix this ash with Crossing Powder, and sprinkle it where you know your target will walk.
To Pact With an Accursed Tree
Many trees are known to hold a vindictive power: some trees are wholly good, some wholly evil, and some work both ways. Amongst these feared and ill-reputed trees are Elder, Fig, Willow, Cypress, Blackthorn, and Walnut. In Italy, walnuts are trees witches make pacts under and swear to the devil. In the UK, Blackthorn is a tree of abject malignance, with reports of witches swearing to the devil, or some other entities under the tree, and pricking their fingers with the thorn. As the prick goes septic, the initiatic fever takes place, and the witch that comes to the other sidew of the fever is brought into the coven. The Cypress is a tree of the dead and mourning: a tree that can gather spiritual vermin and dispel them. Willow is a tree reported for all the evils of the moon, and is a tree reputed of much evil.
When the moon is waning, find one of these trees, and take with you a piece of raw pork, a razor blade, an ink pen (or use Bat’s Blood Ink), Crossing Oil, salt, an Iron Nail, hammer, and Black Arts Self-Igniting Incense Powder.
Write the person's name in Bat’s Blood Ink, or the ink pen on the inside of the packet of paper that the razor blade comes in, and wrap the razor back up. Anoint the meat in Crossing Oil, and suffumigate it in Black Arts Self-Igniting Incense Powder, or a mixture of sulfur, valerian, chili, and black pepper, baptizing it in the smoke:
“I conjure and name you, oh creature of flesh [name], and as you are named as this person, you are in their likeness, even now”.
With the salt, coat the meat on both sides, allowing the oil to make the salt to cling to the meat. Place the razor blade packet in the center of the meat, and roll it away from you. Pin the working together with an Iron Nail, anointed in Crossing Oil. Nail the spell to the tree, and say aloud:
As this meat wastes away,
All the vultures and vermin,
Which shall surely feast,
May [name] Find no peace,
May they be wasted as this meat rots
And wither like the moon,
May their soul go to this tree,
By the devil, and all his legions.”
To Consecrate a Black Book Which Will Be The Liber Spiritus
The goal of the Liber Spiritus or a Little Black Book is a working book that details spirits and operations, but can also serve as a place where the spirit can be called, by placing the seal of the spirit into the book. It serves as a means to pact with a spirit to conjure it faster, once initial rites have been made. Much like a Rolodex to dial an extension faster, rather than calling the King, then the Prince, then the Duke, then the General, then familiar.
The books are made based off whatever grimoire you’re working out of. One infamous and short grimoire that details its instructions is The Little Black Book of the Black Venus, attributed to John Dee. However, this method I have used, hopefully, can inspire you:
On an auspicious day to make the book, whether it be under he light of a full moon, on a particular planetary day, the day of a saint's feast, etc.. take up a new book. Burn Black Arts Self-Igniting Incense Powder, or a mixture of valerian root, wormwood, parsley, myrrh, a pinch of sulfur, and one of these: hellebore, henbane seeds, belladonna, mandrake, or datura.
Suffumigate the book into the smoke, and speak to it:
Saint Cyprian the Mage,
Aid me in revealing the spirit
Which is right and true,
Into this little black book,
To call and command the devils marked within these pages
And Saint Cyprian give to me, the secret name of this book, and its seal and call,
So that I may Call upon it’s Spirit
By The Father and The Son and The Holy Spirit,
Saint Cyprian, Saint of Magic Books
Amen.
You should meditate until the name of the book is revealed, with the sigil and call.
Mark into this with Bats Blood Ink, the seal of the spirit of the book. This spirit will help bind the other spirits to the book, and will help be a famliliar unto you. To give thanks to Saint Cyprian you should burn some of his dedicated Incense.
To Pact With The Kings of Hell To Give You An Imp And Help You
For this you will need a small to medium ceramic or metal vessel, one with a lid. You will need a stone which was auspiciously received and paid for. During the full moon, at midnight or the gallicinium, suffumigate the workspace with Black Arts Self-Igniting Incense Powder.
Mark on the floor the sigils for Lucifer, Astaroth, and Beelzebub in blessed chalk, and over them,

light three candles over each.
Call to Each:
I Conjure You, Lucifer,
I Conjure You, Astaroth,
I Conjure You Beelzebub
Take a piece of paper and with Bats Blood Ink, write onto it:
I write with Bats Blood To The Three Kings of Hell, Lucifer, Astaroth, and Beelzebub, so that you may give me a helper in (XYZ) endeavour.
And with a little blood from you middle finger of your left hand, daub some on the stone. Place this in the center of the three sigils, and place your petition into the vessel with with the stone. With a bit of gunpowder, sprinkle it into the vessel, and with a match, carefully light the gunpowder. You should confirm that the spirit lives in there, or has been birthed in there.
For seven Saturdays, pour over the stone milk with a drop of your blood mixed into it. You should receive from it its sigil and name, which you can call upon to give it tasks.
To break the pact, remove the stone and throw it into a river running west, then destroy the vessel and pact.
