You have a creature of Shadow in your distant ancestry. The exact nature of that shadowblood is immaterial (though it may be a source of adventure), as the overpowering human genetic tide has reduced its
special abilities to a few salient features.
Benefit: You gain a +1 inherent bonus on one
saving throw of your choice. You also gain low-light vision, which allows you to see twice as far as a normal human in starlight, moonlight, torchlight, and similar conditions of poor illumination. You retain the ability to distinguish color and detail under these conditions.
