Bandit: B&E

 is a challenge in Risk of Rain 2. It is completed as by killing the final boss with.

Tips

 * This challenge is fairly self-explanatory, though depending on their items, the player may have to be careful to not accidentally kill from the effects of their items instead of their attack.
 * The challenge can be made easier using, as there will be two copies of the final boss. Killing either one with Lights Out will complete the challenge, so the artifact effectively grants the player an additional attempt.
