Alignment: Neutral Evil
Color Type: Orange - Named Enemy
Attack: Bastard Sword (Slashing + Magic)
Habitat: Valak's Mausoleum — Southwest part on the obrigatory underwater passage, behind a secret door.
Valak's Firstborn was originally a Spectre. Due to bugs involving Spectres frequently flying into walls and never coming out, you often could not get the experience/extra chest for slaying Valak's Firstborn. Turbine took the easy way out and changed him into a Skeleton Knight rather than fixing the bug with Spectres.
