A Create add-on and library that adds a Blood fluid and the means to extract it.
To harvest, place a Basin or Item Drain directly beneath a set of Crushing Wheels. When a mob is crushed, blood is deposited into the collector below.
How much blood a mob yields scales with its max health and its type:
| Mob category | Blood yield |
|---|---|
| Animals, Villagers, Piglins | 100% |
| Arthropods, Creepers, Endermen | 50% |
| Zombies | 25% |
| Bogged, Husk | 10% |
| Skeletons, Golems, untagged | none |
All of these are data-driven tags, so you can re-tier any vanilla or modded mob.
By default, mobs produce 50mB of blood, per point of max health (configurable)
