Reproduction is easy, just pick up a Sacrificial Dagger and rightclick with it near a blood altar. You will see that the altar accumulates LP, but despite the appropriate sound effect, camera flinch, and even the health bar flashing, health is not removed. Also affects directly "using" an orb to directly sacrifice health into your personal LP network. Notably, overdrawing your LP network with a sigil (I tested with a lava sigil) subtracts health correctly.
