Create: Hemodynamics

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)
