The amulet that had been received from Quinn was a blessing to Lucia. It had given her powers and strength to fight in situations where she wouldn't have been able to fight. It allowed her to use blood aura, even though she herself wasn't a vampire.
At the same time, the blood clone was able to get her out of multiple different situations. There was a thing as well, the more blood that was split around her and the more time spent using it, the more powerful the amulet would become.
However, other than using the blood aura, she never really knew how to draw out more power. It was almost as if she could feel there was more power in the amulet but had no clue how to get it out of there.
It made her wonder if she was the right person to have it, if perhaps it would have worked better with a vampire, but this was an heirloom from her family, and Quinn said she deserved it.
