A clot of animate blood the size of a small house, this amoeba of failed life is hungry to add new blood to its oozing body.
The half-congealed blood of past victims gives a blood amniote its form, and its ties to the Negative Energy Plane give the creature animation. Mindless, it seeks only to pierce the fleshy carapace of all living creatures it comes upon so it can draw out the blood beneath.
Though these creatures are mindless, vestiges of past victims completely drained of blood remain imprinted on them. Observers sometimes see these random memories as faces that briefly form on the surface of a blood amniote, only to fall away again to formlessness moments later.
When a blood amniote senses potential prey, it quickly moves to engage, hoping to draw out the blood of its victims in full quantity.
Blood Call (Su): Whenever a blood amniote strikes a living creature in melee combat, its touch causes the target’s body to expel a portion of its own blood through the pores. The expelled blood gathers and flows across the intervening distance between the prey and the blood amniote. This attack deals 1d4 points of Constitution damage to the foe.
If a blood amniote deals as many points of Constitution damage during its existence as its full normal hit point total, it self spawns (see below).
Inescapable Craving: A blood amniote has an inescapable craving (see Undead Metabolism) for blood, which it satisfies by using its blood call ability.
Self Spawn (Ex): If a blood amniote deals as many points of Constitution damage during its existence as its full normal hit point total, it self spawns, splitting into two identical blood amniotes, each with a number of hit points equal to the original blood amniote’s full normal total.
