Artificer: Chunked!

 is a challenge in Risk of Rain 2. It is completed as Artificer by fully defeating a Teleporter Boss in a one-second burst of damage.

Tips

 * One way of getting this challenge would be to get the from the Timed Security Chest while getting damage items like some humble combination of,  and . With these items a synchronized Preon and Charged Nano-Bomb attack would easily kill a single boss-enemy in an instant. This challenge becomes nearly impossible with this setup when multiple boss-enemies spawn. Playing on Drizzle would make single-enemy bosses spawn for more stages. If too much time passes and multiple enemy bosses start spawning it would probably be easier to just start another run.
 * Another viable option is to start the run on Drizzle and use the Command Artifacts to stack at several Armor-Piercing Rounds (at least 5), plus a few Crowbars the first and second stage and repeatedly reset until the first boss drops a boss item from which you choose Genesis Loop. Then during the second teleporter event allow the boss to hit you until Genesis Loop procs and it should instantly kill the boss, one benefit of this method is you do not need to spend Lunar Coins, though getting a boss item on stage one is inconsistent.
