Artificer: Massacre

 is a challenge in Risk of Rain 2. It is completed as Artificer by performing a multikill of 20 enemies.

The multikill counter resets after 1 second without killing any enemies.

Tips

 * Using a is a great way to gather enemies together and setup a big multikill. Combine it with several  for maximum effectiveness.
 * The Gilded Coast environment makes this challenge nearly trivial in combination with the above tip, as Lemurians spawn incredibly quickly. The best method is to do this challenge before activating Aurelionite, so there is no conflict of trying to dodge attacks or lower the boss' health at the same time.
