Strigoi are bad with items of faith. It doesn't have to be a cross or a Star of David. Any symbol that someone believes in can work to repel you.

You're more fragile than you know. That's a bad position to be in. You know that right?

Maybe you can't feel for others but your own self-preservation ought to have you reconsidering going back to how you were. At least then you knew your limits, you knew your weaknesses and your strengths.

What you don't know can get you killed.
