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
Documentation is provided via an in-game book managed by Guide API under the name "Sanguine Scientiem".
Art
You may notice the mod has an entirely different look than you may remember. These textures were graciously provided by the Unity 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.

So Cry of the Eternal Soul is not working, am i correct?
What is the use for the sanguine science my and is there a way to use it without guide api.
i found a bug in 1.7.10. it seems every release got this bug. but when i search on the net, there is no such condition found.
when i press shift, use the Sacrificial Knife to die, the sever crash and say "illegal stance" . besides, i played in offline mode.
and i tried your latest mod in 1.12.2, with Guid-API, it didnt work. maybe the bug still exsist? (only tow mods and latest forge)
only the latest bloodmagic for 1.7.10 and forge 10.13.4.1614 loaded in Minecraft 1.7.10
the illegal stance i found in logs is below. (everytime the same however i die)
[06:15:53] [Server thread/WARN]: 111 had an illegal stance: 0.019999995827674866
In reply to rtxyd:
I don't care about the 1.7.10 part. What about the 1.12.2 version "didn't work"?
In reply to DatNut:
OK, this is the crash report at that time. at the end of forge mods loading step 1.

In reply to rtxyd:
Your Forge is more than 300 versions out of date.
In reply to DatNut:
Oh, that is ..so dissapointing, i just downloaded it recently. and thank you. sorry to waste your time.
it works, and i just forgot to change the version of forge.
please add guide-api as required dependency
In reply to cryptearth:
Good news, it already is one and has been for 3 years now.
In reply to DatNut:
ok, if you select a specific file for download - yes, it also shows up for me, but if you click on "relations" it doesn't show up for the project
I guess that's an issue with curseforge backend not sync the project requirements with individual files ?
would be nice to add it as project dependency it shows up also when you click on relations
In reply to cryptearth:
The project dependency page is managed by Curse. Never rely on it for any project. Always go by the individual files.
In reply to DatNut:
Yea, already reported to curse support to check this. IDK about settings as I don't have a project up myself - but in addition to file based settings isn't there any option to also set dependencies for the whole project?
// edit
Maybe curse is parsing it wrong as the last "release" file is for 1.7.10 - wich didn't depended on guide-api. So I guess, setting a current release for 1.12.2 may would update it?
In reply to DatNut:
support redirected me to feedback: https://twitch.uservoice.com/forums/915910-game-mods-curseforge
will file a report there
question is there a way to have an upgraded coat of arms that holds more lp in it?(aka the chest armor that gains lp for every mob killed) the kind of upgrade i'm hoping for is so it can hold more lp thats all i'm hoping for. eather in the mod it's self or an addon. if not how hard would it be to make said upgraded coat of arms code wise as i'm willing to try to make it my self.
Hey: D, I'm a fan of blood magic it's my favorite mod but I have a proposal it actually it would be nice if with a ritual we can have a little power to do a little energy shield (I see it red with a kind of energy in our hands) that could protect us and our friends who are in trouble thx and I am fan of blood magic
Hi~
Can someone please tell me how to fix the bug that when I use divination sigil or seer sigil right click to the air, these messages come on to chat instead of the information about my lp in my soul network.
“tooltip.BloodMagic.sigil.divination.currentEssence”
“tooltip.BloodMagic.sigil.seer.currentEssence”
The version I'm using is 1.12.2-2.4.1-103
I love this mod very much but this bug made me hard to play with it ._.
I found out that this bug happened only when I use traditional Chinese as a language in the game. Thanks
Is there any reason that in the latest version I should be losing basically all my lp in my soul network when I only have a lava crystal created? Im not even using the lava crystal.
Edit: It seems that looking inside the furnace that contains the lava crystal just drains my lp?
In reply to dimgam7:
Hi, the Lava Crystal is used in the T3 Altar to create a Weak Activation Crystal which can activate a lot of Rituals. However you don't need the WAC to obtain the Awakened Activation Crystal which can activate all Rituals (as far as I know), so I guess you can skip it but that might slow your progression.
And when the Lava Crystal is used as fuel, each item cooked will drain 50 LP (at least, that's how it is supposed to works and how it works for me : if you have LP drained simply by looking into the Furnace (without anything cooking), you may have a problem).
NB: I use the latest version too (2.4.1-103)
