Vampires take an extra 5 hearts of damage from Holy Alloy weapons. If they are attacked from range or cannot get to you they will turn into a bat and fly to you. They give a distinctive laugh when a player dies in close proximity. If the player is killed by them, an infected carrying their gear will spawn. Vampires rarely spawn wielding a Dark Iron Dagger. and/or pieces of Night-cloth Armour which may be dropped (25% for each item carried).
