Gruesome? Probably. Worth it? Definitely! 
Have you ever picked up a magic mod for Minecraft, and thought that it was too tame? Was there not enough danger involved when creating your next high-tech gadget? Bored with all of those peaceful animals just staring at you without a care in the world? Well then, I am glad you came here!
Blood Magic is an arcane art that is practiced by mages who attempt to gather a vast amount of power through utilizing a forbidden material: blood. Even though it does grant a huge amount of power, every single action that is performed with this volatile magic can prove deadly. You have been warned.
For the best experience, you should install JustEnoughItems to find your way through the recipes.

Getting Started
Getting started in Blood Magic has changed slightly since 1.7.10. Rather than finding a Diamond to craft a Blood Altar, you need to obtain some Demonic Will. To get your first bit of Will, you'll need to craft some Soul Trumpets Snares and toss them at enemies. If you're lucky, this will snare the enemy. When killed, snared enemies will drop a small amount of their Will. I'll let you take it from there.

Documentation

Art
You may notice the mod has an entirely different look than you may remember. These textures were graciously provided by the Unity team.
Team
WayofTime
Way works on all the cool content you get to play around with as well as writes the guide. Can usually be found making a mess for Nut to clean up.
TehNut
Nut is essentially a maid. He primarily works behind the scenes, making sure the codebase itself stays as clean and optimized as it can. He's also in charge of most of the work involved in porting to new Minecraft versions. Can usually be found committing code in the wrong bracing style.

Just posting as a reminder that the lapis block lesser ritual still uses "/time set" to change the time of the world, and that because of a minecraft bug that sets it to DAY ZERO and that time, causing problems with local difficulty, season mods, time passage based mods (Astral sorcery) and a number of other functions.
So I am once again requesting that the nightfall lesser ritual stone be changed to use /time add with a bit of math that requsts the current time, and then adds the required minutes to reach the desired time.
I've been having a bit of trouble with using the ritual diviner and the elemental inscriptions lately. No matter what I do with the ritual diviner it doesn't let me load in rituals that I've previously used before but I don't know if this is an error on my part or not.
Also with the elemental inscriptions I haven't been able to recharge them even though I'm already bound to them. Am I doing something wrong?
There is a bug in v.1.12.2-2.4.0-102, when arrow shot from sentient bow (destructive) touches block it continues to explode until picked up.
In reply to trekoff:
Have you tried updating to a version that has that fixed? That might fix your problem.
In reply to TehNut:
It's just in case that it wasn't fixed or found in other versions.
Thank you a lot for the continued work on this mod- Blood Magic has been a labor of love, and it is extremely appreciated from all of us who've played over the years. While it surprises me the 1.12 version is still in beta, I don't mind as the relatively recent and frequent updates suggest that you're working to ensure an optimal version with few (if any bugs). Thanks guys! Raising a mug of fresh villager blood in your honor!
What makes this mod in beta? Are there features that are going to be put in it later, which would make it incompatible with current versions? It being in beta makes me hesitant to give it a try, as much as I want to.
Hey, anyone know how to download the older versions of blood magic? This seems to be the only mod website not trying to give me a virus.
In reply to jenkinsboyo:
Go to the files page and download the older versions. This is the only site you should be downloading mods from.
My apologies for asking a question that has probably been asked a million times so I'm sure you know what is coming next, but... Are there plans to update Blood Magic (the greatest mod ever) to MC 1.14.4
In all fairness, though, I read a post where you (TehNut) excoriates a player for using a version older than 1.12.2 and I quote " Your Forge is more than 300 versions out of date." well sir I must say it seem a little odd that you would go there, as and I quote "Your blood Magic is 125 versions out of date" how about an update.
In reply to MikeMcBurn:
Not sure why you would continue to ask a question you felt the need to apologise for in advance. With minimal research, you can see that there is a WIP 1.14 branch on the GitHub.
I'm struggling to understand how these two correlate. One involves somebody using an ancient version of a library while the other involves me not having finished a job that will take several tens of hours.
I'm also very concerned with where you pulled the number of version Blood Magic is "outdated" by. My number was an actual fact, while yours seems to be pulled from your ass to attempt to make a point.
If you would like BM to be available for 1.14 soon, rather than when I have free time to dedicate to it, please DM me and we can work out a fair hourly wage that you can pay me to do so.
Nice
my game keeps crashing because i need guideapi, so do i need to upgrade my forge?
In reply to ThemoocowYT:
0. Locate this page: https://www.curseforge.com/minecraft/mc-mods/blood-magic (you probably already did this)
1. Read the project description page (you probably have not done this yet)
2. Locate the section "Documentation"
3. Find a familiar appearing pair of words that reads "Guide API"
4. Click the link to the Guide API project page
5. Locate the "Recent Files" section
6. Download the latest version of Guide API that has been released for your Minecraft version (probably 1.12.2)
7. Pay more attention in the future and read the documentation that is provided to you.
In reply to keraldi:
I figured it out a bit ago when i looked at the description. But either way, thanks for the help.
Hello, I want to use this mod with the Vampirism Mod. Do I need anything to use your mod?
Edit: Sorry, I just found out how. But if there is anything to make it work better than it already is please tell me!
Is there a way to make only vampires able to use blood magic?
Great mod, thanks!
