So is the Goblin Kin Talent nocturnal just the GM description of their ability to see at night minus the daylight damage?
Here's the text verbatim:
THE GOBLIN TALENT: NOCTURNAL
Goblin prefer the night and hate daylight, which hurts their eyes. They can see in the dark and talents are thus not affected by darkness at all (see page 112). Also, when rolling for STEALTH in a dark or dimly lit environment, you can spend Willpower Points which are automatically turned into extra x. You may even roll first and spend WP after you see how the roll goes.
