Ash sighed and looked about as embarrassed as he was capable of.
"…I'm really not that good at blood magic; I never have been. I was practicing before we left and could only add a couple of feet at most. Watch."
He closed his eyes and his brow furrowed in concentration as he cast the spell. The normally invisible barrier glowed red and Ruby was able to see it slowly inch its way toward a dome shape before stopping.
Ash opened his eyes and glanced up at it in defeat before turning to her. "See? Only two feet higher. Now take a hold of my arm and see the difference."
She rested her hand on his inner elbow and watched him do the exact same spell casting hand signals as before but this time the magic extended hundreds of feet above the castle and closed. They were encased in a giant red bubble that shimmered and disappeared once he put his hands down.
Ruby was amazed. She actually had an effect on vampire magic! But why?!
