*** IT IS ALPHA STAGE OF THIS POWER ***
As you can see - It's a vampire polymorphing into a bat.
You may have noticed that It's a crow flying not a bat! I used hl2 crow model to test it, however It'll be replaced! Also I'm planing to do some effects and etc, so It's more realistic.
And the power will be balanced - It'll make you very vulnerable. And it won't last for ages. etc...
