Uterus

A mechanical puppet resembling a medical mannequin, the Uterus carries an embryo within it that will crawl out to attack the player. Like other creations of Valteil, Uteri are soulless.

Lore
"'Valteil the enlightened one created many forms of life for many different purposes. Uterus serves a purpose too and every night Valteil would summon one of them to his quarters.' - The New Gods when asked about the Uteri."It's suggested that Valteil uses them to satisfy his own needs, and possibly using the Embryo too in his depraved acts, since Nas'Hrah suggests Valteil is a pedophile.

Strategy
The Uterus is not the true danger, but the embryo is as it will deal a lot of damage to the player if left to crawl towards them within a few turns. Take out the Uterus quickly before the Embryo has a chance to attack and damage your party members, and possibly unsettle the player themselves.
