- "As daylight chases darkness, the vampire's power wanes."
Sunlight was the name given to natural light radiated by Nosgoth's sun. In context as a gameplay-related term, it featured in Legacy of Kain: Soul Reaver. Raziel could make use of sunlight in his skirmishes against the vampires of the events of Soul Reaver, to whom it was hazardous; many subtypes of these vampires would be fatally wounded upon coming into contact with the sun's rays.
Sunlight is a useful hazard to exploit when fighting fledgling vampires, adult vampires on the other hand aren't visibly affected by it.
The Rahabim are especially vulnerable to sunlight (as even adult Rahabim are burned when they are exposed to it).
