Because, traditionally, stakes have been used to impale vampires to their graves and serve as a method of vampire destruction.
A vampire should avoid sunlight, as it can cause severe burns or even death. Holy symbols, such as crosses or sacred water, are also dangerous, as they can repel or harm them. Additionally, entering a home without an invitation can provoke hostility from its inhabitants, making it a risky move. Finally, they should steer clear of garlic, which is traditionally believed to ward off vampires.
You should just act normal. And if you need to know if he/she is a vampire. Joke about that she/he is a vampire
find him or her sucking a cow's blood. no... the vampire should be really thirsty and attempt to suck the non-vampire friends' blood.
they should avoid vervain if a vampire touches it, it will burn them if they drink a persons blood who has consumed vervain in the past three days the will fall to the floor to weak to stand writhing in agony foaming at the mouth and will become rabid.
Garlic and wooden stakes. Hope this helps!=Ariel (The Little Mermaid)=
Does he go into the sunlight? Does he avoid you so he won't drink your blood? Find these out and you might have a vampire on your hands.
In mythology, vampires avoid sunlight, crosses, holy water and sometimes water. Overexposure to any of these can kill a vampire. In reality, vampires mainly avoid sunlight/bright light and loud noises. A vampire in reality has heightened senses and has great difficulty tolerating solar radiation. Non-fiction vampires can be killed in the usual methods.
The vampenze kill their pray before they drink; vampire do not, they knock them out, and take a sip. When a vampire crosses paths with a vampeneze, vice versa, their ways may get them into battle.
