This technique allows one to mark an object with a measure of Vitae, and cloak it from sight as through use of Touch of Shadows, but the sacrifice of Vitae extends the duration of the effect for an entire night, and doesn’t require the vampire to remain present. The vampire rolls for this effect, and then the results are compared to that of any searchers who encounter the object for the remainder of the night.
The effects are otherwise identical to Touch of Shadows, save for the cost of 1 Vitae.
