Umbral Agility not showing darkness damage pen bonus

[ohhellothere]

Idk if there's a reason for this, but when I put a point into umbral agility the accuracy and defense bonus show up on my char screen, but the darkness damage pen bonus doesn't

Correct, it is visually bugged and doesn't show up on the character sheet unless you have any other source of darkness pen%
