Blood Magic

Core concept and progression loop Blood Magic centers on a single resource called Life Essence. You generate it by damaging yourself or sacrificing mobs at a Blood Altar, then spend it to craft sigils, bound armor, and ritual stones. Every major action drains essence; if you run dry the mod pulls from your health instead, so miscalculations can kill you. The loop rewards planning: build a safe altar, automate mob collection, and keep a buffer of essence before you attempt expensive recipes. ## Key systems The Blood Altar is the entry point. Tiers one through six unlock progressively stronger recipes and larger essence storage. Sigils are handheld tools that consume essence for effects like flight, block placement, or combat buffs. Bound tools and armor upgrade with essence instead of experience, and they repair themselves from your network. Rituals are multi-block structures that run continuous effects - ore generation, mob spawning, crop growth - at a steady essence cost. The mod also adds a music disc and a set of decorative blocks for altar aesthetics. ## In-game documentation A Patchouli guide called the Sanguine Scientum ships with the mod. Craft it with a book and a piece of glass to unlock a full recipe browser, a getting-started tutorial, and reference pages for every ritual and sigil. The same content is mirrored on the web for players who prefer reading outside the game. ## Compatibility and requirements Blood Magic runs on Forge only. The current release targets Minecraft 1.20.1 and requires the mod on both client and server. No other mods are mandatory, though Just Enough Items is recommended for recipe lookup.

It fits tech-magic modpacks where automation can offset the danger, and it appeals to builders who want a distinct visual style for their magical infrastructure.
