Gassaruma

The Gassaruma is a plant that is very helpful when fighting zombies, especially when doing it with Snapdragons or Torchwoods. When the oil is lit on fire, it burns for a while, dealing 2 damage a second to afflicted zombies. Any non-oiled zombie that wanders into the burning oil spill, they are dealt 1 damage a second. Zombies also take damage when they initially slip in the oil, which is how they get covered in the oil. Slower zombies take less damage. Refer to the chart:
