“Nocturnal” is an acquired template that can be added to any humanoid or monstrous humanoid (referred to hereafter as the character). It uses all the character’s statistics and special abilities except as noted here.
The nocturnal template allows the character to function in darkness the way normal humans do in the light. A character acquires the nocturnal template by undergoing a course of gene therapy (see More Human than Human). The regimen requires 25 successful Fortitude saving throws (DC 20).
Special Qualities: A nocturnal retains all the special qualities of the character and gains the additional special qualities listed below.

Skills: Same as the character, with a +2 species bonus on Listen and Move Silently checks.
Feats: Nocturnals gain Blind-Fight as a bonus feat.
