Lasombra & Cast No Reflection
Silver was considered a holy metal and the reason why vampires traditionally didn't show up on mirrors was because they were rejected by the metal in their unholy state. Typically on a MU* the Cast No Reflection or Lasombra clan flaw tends to manifest more as a "Get away with whatever the fuck I want" merit and thus we are modifying it to be an actual flaw as follows:
Cast No Reflection (on its own): You do not show up on mirrors (they are backed with silver) and film cameras (they use silver halide) as a reflection of the folkloric properties of silver. But, you do in fact show up on reflective surfaces that don't involve silver (they show up in the gloss of a window or the still surface of a lake) and you show up on digital cameras (they use photosensors, not silver halide).
Clan Lasombra as a whole: To mitigate very weakened impact of Cast No Reflection, your Lasombra is considered to have the Vulnerable To Silver flaw automatically.
