That Is the Evilest Thing is an achievement in The Witcher 3: Wild Hunt and requires one to use a burning opponent to ignite the gas from a Dragon's Dream bomb, causing a small explosion, 10 times.


  • Simplest way is to use Igni to set an opponent on fire, then throw the bomb at them.
  • It's important to note that opponents don't have to die from this.
  • As you can only carry 3 bombs by default (more depending on abilities), you may need to meditate to replenish them after each run.
