Blood Magic

Blood Magic is a magic mod created by WayofTime. A dark magic mod revolving around a blood-powered altar system, sacrificial rituals, living armor, and demonic will. As a magic mod it concentrates on spells, rituals, and arcane progression, and it has been downloaded around 50 million times, which puts it among the options players reach for in this space.

Blood Magic is built for players comfortable with a risk-and-reward magic system fuelled by life essence. Rituals and tools draw on a Blood Altar and Soul Network, trading health and sacrifice for powerful effects, which gives the mod its dark, deliberate pacing. It is a deep, systems-heavy mod, and getting the most from it means investing real time in its mechanics.

The mod is available for Forge and NeoForge, so it fits a range of modpacks and launchers. It currently targets Minecraft 1.20.1. It runs on both the client and the server, so on a multiplayer server every player who connects needs it installed alongside the server itself.

Blood Magic works particularly well alongside Just Enough Items. It targets the Forge side of the ecosystem, so it fits comfortably into Forge and NeoForge packs.

Being a content-rich mod, Blood Magic adds machines, entities, or world features that can affect performance in very large bases, so pair it with optimisation mods if you run a big pack.

If you are comparing options, similar mods include Thaumcraft and Occultism. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
