Challenge: #20 Purist
Description: The Purist challenge requires you run to Womb II to defeat Mom’s Heart.
Unlock: This Challenge is unlocked by defeating Mom for the first time.
Starting Items: There are NO starting items for this challenge.
Strategy: This challenge starts you off just as it sounds, with nothing. Which isn’t much different than starting a normal run with a character, but there are no item rooms to help your build. It will be important to help your chances with Devil Deals/Angel Rooms, looking for secret and super secret rooms and utilizing shops to the best of your ability. If you can utilize curse rooms, without sacrificing any red health, it will be worth the heart to check to see if anything can help you along your way. Anything to help you acquire more bombs, such as Mom’s key or the Humble Bundle, will come in handy for looking for your secret rooms or bombing tinted rocks for soul hearts to help protect your red health. Taking advantage of the challenge rooms, regardless of what’s in there, will help as far as having resources or possibly having an item to help with your damage. Playing it safe and having a little good luck with your RNG will have you completing this challenge without too many problems.
Completion: Completion of this challenge unlocks the Rune of Berkano.
