Interested. Does the activation cost have to be blood?

No. Bleeding to activate the power is just a suggestion but it has to be something negative. Like with my guy, the cost is a slow but steady decline of his mental state. As long as there's some cost to using the powers it can be whatever you want and can be different for everyone.

But maybe run it by Acer first as I'm not the GM of this. I'm just answering these questions because Acer has gone over this stuff with me before this thread was posted and...well I'm here.
