Deicide

Deicide is a challenge in Risk of Rain 2. The achievement is obtained by defeating an Elite boss on Monsoon difficulty.

Tips

 * When done in multiplayer, only the player who deals the killing blow to the boss will unlock this achievement.
 * Although time-consuming, if you are having trouble with this challenge, you can always keep restarting the game and checking the first stage for a mountain shrine. If this spawns an Elite boss, it should generally be easy to kill.
 * If the Elite boss is easy to dodge, you can always ignore it and kill all non-boss Monsters until the Teleporter is at 99%, then have only the boss on its own to deal with.
