Vampires in most legends and pop culture have several iconic weaknesses that make them dangerous but not unstoppable.

Classic weaknesses

  • Sunlight: Often burns, weakens, or completely destroys vampires, which is why they are usually nocturnal and avoid the day.
  • Wooden stake to the heart: Piercing the heart (often with wood) is a common way to immobilize or kill a vampire in folklore and modern fiction.
  • Decapitation and fire: Many modern stories treat vampires like other undead—severing the head or burning the body is considered a reliable way to finish them.

Repellents and barriers

  • Garlic: The strong-smelling herb is said to repel vampires, keeping them from approaching or entering a room, though it doesn’t always “harm” them physically.
  • Holy symbols: Crosses, crucifixes, holy water, and consecrated ground can repel, burn, or weaken vampires in many Christian-influenced stories.
  • Running water: Some tales say vampires cannot cross running water or are weakened or destroyed if they attempt to do so.

Invitation and resting place

  • Need for invitation: In many traditions, a vampire cannot enter a home unless someone who lives there invites them inside.
  • Vulnerable in the coffin: When resting in a coffin or native soil, vampires are usually at their weakest and can be destroyed more easily during the day.

Obsessions and “quirky” weaknesses

  • Counting compulsion: Older European folklore sometimes gives vampires a compulsion to count small objects (like grains or seeds), which can be used to distract them.
  • Customized weaknesses: Modern games, fiction, and forum worldbuilding often give each vampire a unique personal weakness (like a specific flower, type of music, or irrational fear) to keep them from being too overpowered and to make each one a kind of “puzzle monster.”

TL;DR: Vampires are usually brought down by sunlight, damage to the heart, decapitation or fire, and are held at bay by garlic, holy objects, running water, and rules like needing an invitation—plus lots of newer stories add quirky, custom weaknesses to keep the trope fresh.
