Requires: Scion background
The deeper you embrace your shadowy heritage, the more it marks you. Some changes are subtle, while others are impossible to hide. When you are in dim light or darkness, you gain a +1 bonus to your spellcasting checks and your spellcasting Save TN.
Corrupted: Increase the bonus to +2, but roll 1d6+4 on the Corruption table for your Bloodline.
