Blood Ward

You channel your blood magic to protect your body from harm. Extending your hand, you create a body-sized magical shield that can deflect magical attacks and reduce physical damage. Your walking speed is cut in half, and you are vulnerable in the opposite direction of where you hold the ward. Magical attacks have disadvantage on you, physcial attacks are cut in half, and you have advantage on STR and DEX saving throws against magic. 

For every spell level higher you cast this at,  you can include one other creature in this ward.
