Strategy

 * Tears fired are huge and do high amounts of damage, meaning it is not difficult to kill an enemy if there is a clear shot.
 * Thanks to Cupid's Arrow, tears do not disappear when hitting an enemy.
 * My Reflection will shrink the range of tears considerably, to about half a room. A little practice is more than enough to accommodate it.
 * The biggest worry in this challenge is large amounts of Obstacles. This can be mitigated by spectral tears, such as those granted by or . These items can be found in a Devil Room or Angel Room, respectively.
 * can be considered as a high risk, high reward item to get in this challenge- while it must be fought with almost exclusively at melee range (due to its excruciatingly long charge), it deals enough damage to where it can one-hit kill almost all enemies (including bosses).
 * spawns flies that deal twice the starting damage, making them extremely effective weapons.
 * will kill most enemies and early-game bosses instantaneously (as soon as they enter the area of its damage).
 * will allow Isaac to rapidly fire large shots that each still deal high damage.
 * fires 10 high power shots, making it an easy option for clearing the challenge.
 * 's swings scale off of Isaac's damage, and are not affected by tear delay, resulting in quite a useful weapon.
