Challenge: #15 Slow Roll
Description: The Slow Roll challenge requires you to run to the Depths II and defeat Mom.
Unlock: This challenge is unlocked by default.
Starting Items:
Cupid's Arrow
Polyphemus
My Reflection
Strategy: This challenge is pretty straight forward. You shoot a giant triangular shaped tear, with piercing, that pretty much decimates most enemies. Your tear rate is very low, so you will be looking for any kind of Tears Up item or if you are lucky enough a Tears Up pill. With my reflection your tear range is diminished, so some range items will allow you to keep a little more distance from enemies when clearing rooms.
Completion: Completion of this challenge unlocks the Swallowed Penny.
