HEY PERSON ARE YOU THERE!?!?!?!?
I equipped the shield while having normal Vampirism on 360, and I can bash, level up block, and my arm is held out, but I can't see it. It's in my inventory, though and I can drop it. Not gonna cure Vampirism just yet, and I'm not a Block-based character, so it doesn't faze me too much.
