Blood Smeltery

Blood Smeltery connects Tinker's Construct with Blood Magic. Right-clicking a tank that holds tartaric gems draws out demonic fluid, which can then be poured into casting molds. Demonic fluid mixed with blood yields life essence, liquid glass and soul sand, while blood-seared stone alloyed with seared stone produces life essence, blank runes and blank slates.

The mod adds a bloodbrass alloy made either by alloying molten copper with life essence, with higher life essence giving a higher tier, or at a blood altar. Tools made from bloodbrass gain the exsanguinate modifier, which adds life points to the soul network whenever a monster is slain. Tools and weapons with the bloodstained modifier repair themselves from the soul network for a lower cost, and higher-tier tools gain more base health from the monsters they strike.

Two further modifiers extend tools. Sentience, applied with a tartaric gem, makes a tool act like a sentient sword or pickaxe, and slain monsters drop demon power depending on the amount and type of demon they possess. Divination uses a Divination Rune or Seer's Rune to make a tool behave like a rune, saving inventory space. Installation requires Forge or NeoForge on 1.20.1, and the mod runs on client and server, so the server and every player need it.
