The dark and mysterious Shadow geminate serpents are seldom seen, living in the shadows, their onyx scales helping them blend into the dark. These serpents are born of the shadow and cannot move outside of them. A shadow geminate serpent outside of the safety of a shadow will take 2d8 points of damage every round they are in direct light. Dying in the light will immediately reduce their bodies to ash. Shadow geminate serpents Move Silently as a Thief of double its age category, often using this skill to pick victims off the back of groups. If detected, they are likely to flee, trying again later, when the prey is less watchful. Their breath weapon mimics the effects of the darkness spell, with a duration of one turn per age category of the serpent.
