Bandit: Sadist

 is a challenge in Risk of Rain 2. It is completed as Bandit by killing a monster with 20 stacks of Hemorrhage.

Tips

 * A monster with a lot of HP, most likely a boss, will be required for this challenge. You might need to wait for later stages in order to find an adequate target. Shrines of the Mountain can help summon stronger teleporter bosses early on.
 * will greatly help by stacking uses of Serrated Dagger.
 * Having 2 will reduce the cooldown of Serrated Dagger to 1 second, allowing you to spam the attack.
 * Serrated Dagger only causing hemorrhaging on critical strikes, can help negate the need to perform backstabs to apply stacks of Hemorrhage.
