Start as Character Judas iconJudas with Collectible The Book of Belial iconThe Book of Belial,Collectible Chocolate Milk iconChocolate Milk and a damage bonus of +2 giving him a starting damage of 8.71. Missing any shots causes Judas to take damage. Treasure rooms are present in this challenge. The goal is to defeat Boss Isaac ingameIsaac.

Difficulty[ | ]

Not hitting anything with tears causes Judas to take damage. This makes accuracy very important as missing a few shots can deplete his health very quickly. Because of this, fast-moving enemies or enemies with erratic movement patterns can prove to be very difficult in this challenge.

Strategy[ | ]

  • Hitting any type of poop, fire, bomb, eternal fly, white champion enemy, spike block, or Stone GrimaceStone Grimace does not count as a miss.
    • Hitting any type of poop with a spectral tear counts as a miss.
  • If firing a tear and leaving the room before it touches the wall or floor, Judas will not take any damage. This is only useful if he shoots accidentally.
  • For enemies that move erratically, try and get close enough so they'll close in. Once they approach, move out of the way and shoot them once they stop.

Good Items[ | ]

  • Collectible Toxic Shock iconToxic Shock can help Judas to bypass most of the rooms without the need to fire tears.
  • Obtaining Collectible Fate's Reward iconFate's Reward and charging your tears, but never firing, allows you to fire tears without fear of self-damage.
  • Items that negate damage are extremely useful. Collectible Holy Mantle iconHoly Mantle, in particular, nullifies 1 hit of damage per room, allowing more room for error.
  • Taking Collectible Technology 2 iconTechnology 2 and never releasing the fire keys, even across floors, allows Judas to engage enemies without firing any tears.
  • Taking Collectible Rubber Cement iconRubber Cement is recommended, as hitting a wall won't deal damage to him, and hitting the ground won't either if an enemy is hit first.
    • Enemies include stone grimaces, unkillable enemies, fireplaces, poop, and bombs.

XboxOne Poop is not considered an enemy if it is the first object hit.

  • Collectible Proptosis iconProptosis allows Judas' shots to miss without dealing damage as long as they don't hit a wall or object.
  • Collectible Isaac's Tears iconIsaac's Tears do not count as a hit/miss, and it maintains Chocolate Milk's charged damage bonus when activated, making it a safe combat alternative.
  • Collectible Dead Eye iconDead Eye benefits from this challenge, since the player will be focused on not missing. This can allow for long streaks at high damage.
  • Collectible Tractor Beam iconTractor Beam keeps tears in a straight line in front, which is very helpful for hitting many later enemies.
  • Collectible Ipecac iconIpecac's explosion radius make it much easier to hit enemies, though like in any other situation with the item, caution should be exercised.
  • Spectral tears effect might help, since going through a rock doesn't count as missing.
  • Collectible Pupula Duplex iconPupula Duplex is helpful, since it gives Judas' tears a bigger hitbox, in addition to spectral tears. Flat WormFlat Worm also gives a bigger hitbox.
  • Similarly, Collectible Polyphemus iconPolyphemus gives tears a bigger hitbox and allows Judas to hit many enemies with each tear. Any Polyphemus tear that continues after hitting an enemy won't damage Judas if it lands untouched afterward.
    • Collectible Continuum iconContinuum will help, giving spectral tears and allowing tears to go through the walls to get back on the other side.
  • Piercing shots could be useful since the shots won't damage if at least one enemy is hit, and multiple can be hit with one shot.
    • Collectible Death's Touch iconDeath's Touch is especially useful because it increases the size of tears significantly, making it harder to miss, in addition to piercing and higher damage.
    • (in Afterbirth † and Repentance)Collectible Eye of Belial iconEye of Belial does not damage Judas as long as he hits at least one enemy, making the item very useful.
  • Collectible Brimstone iconBrimstone, Collectible Epic Fetus iconEpic Fetus, Collectible Mom's Knife iconMom's Knife, Collectible Technology iconTechnology, Collectible Tech X iconTech X and (in Repentance)Collectible Spirit Sword iconSpirit Sword won't damage Judas for missing enemies.
  • Collectible Mom's Wig iconMom's Wig will keep spawning friendly spiders until there's 5 of them when charging the shot.
    • The same goes for the Guppy transformation or Collectible The Mulligan iconThe Mulligan.
      • Be careful, however, as there is the possibility of friendly spiders/flies killing a target before Judas' fired tear connects.
    • The same goes for Collectible Number Two iconNumber Two and Collectible Bob's Brain iconBob's Brain, as spawning bombs under Judas while charging and the explosions from the brain, respectively, can easily end the run.
  • One well-timed charge of the Collectible White Pony iconWhite Pony could be enough to insta-kill Boss It Lives ingameIt Lives and seriously damage Boss Isaac ingameIsaac.
  • Tears that have passed through an (in Afterbirth † and Repentance)Collectible Angelic Prism iconAngelic Prism familiar do not deal damage to Judas even if all the split tears miss.
  • If you find Collectible Butter Bean iconButter Bean, do not leave behind bomb-giving items such as Collectible Pyro iconPyro. Placing bombs and pushing them towards the enemy with a fart is a viable alternative for shooting tears.
  • Watch out when using unidentified pills, as R U a Wizard? can be disastrous to the run if not extremely careful and/or lucky. Check the shops for a Collectible PHD iconPHD, just in case.
  • Collectible The Wafer iconThe Wafer makes the challenge much easier in WombWomb and beyond, as it halves the damage dealt from missing tears.
  • Any item that helps refill red heart containers such as the Collectible Yum Heart iconYum Heart, Collectible Maggy's Bow iconMaggy's Bow, and Collectible The Jar iconThe Jar will be helpful in case misses are frequent.
  • Items that grant homing tears, such as Collectible Spoon Bender iconSpoon Bender and Collectible Sacred Heart iconSacred Heart, can make accuracy a lot easier. Although Collectible Godhead iconGodhead is a bad item for this challenge (see below).
  • (in Repentance)Brain WormBrain Worm can redirect misfires back into enemies, thus being a great mistake preventer.
  • A very good strategy is to combine many different followers such as Collectible Mongo Baby iconMongo Baby, Collectible Rotten Baby iconRotten Baby or Isaac's HeadIsaac's Head, and only using the tears from the followers as Judas' main source of damage. This is complimented by items such as Collectible Daddy Longlegs iconDaddy Longlegs as Judas does not have to fire tears to deal damage with these followers.
    • Because of this, Collectible BFFS! iconBFFS! is a very useful item.
  • Collectible The Boomerang iconThe Boomerang will not cause damage if it misses, making it an effective alternative to tears given Judas' high damage.
  • Collectible The Ludovico Technique iconThe Ludovico Technique is an extremely valuable item since the tear never lands, thus Judas can't be hurt if it misses.
  • (in Afterbirth † and Repentance)Collectible Lachryphagy iconLachryphagy's split shots do not count as missed tears. Since your tears will always explode into split shots instead of hitting the ground, Judas will only take damage if the main Lachryphagy shot hits a wall.
    • Having Spectral tears with Lachryphagy will prevent your shots from ever hitting the floor or walls, completely removing the penalty for missing.
  • (in Afterbirth † and Repentance)Collectible Haemolacria iconHaemolacria can be powerful, as only the initial tear needs to hit an enemy; the burst tears do not count, unlike for other scatter shot items.
  • (in Afterbirth † and Repentance)Collectible Shard of Glass iconShard of Glass's blood shots do not deal damage to you if they miss, making this item potentially very useful in this challenge.
  • (in Repentance)Collectible The Intruder iconThe Intruder's quad shot does not count as hits/misses, and taking damage, including damage from a missed shot, summons the more effective active familiar.
  • (in Repentance)Collectible Stitches iconStitches can be used to dodge damage from missed shots if timed correctly. Its teleport can also be used as damage so you don't have to risk missing shots.
  • (in Repentance)Collectible 120 Volt icon120 Volt removes the need to fire tears at enemies in normal rooms, allowing Judas to destroy crowds of enemies just by walking by them.
  • (in Repentance)Collectible C Section iconC Section will not harm Judas as long as the tear hits an enemy before landing, making it a very powerful item for this challenge.
  • Collectible Glass Cannon iconGlass Cannon is recommended since cannon ball tears need to hit only one enemy in order to not deal damage to the player. It also shoots bigger tears than normally to due the high starting damage.
  • (in Repentance)Collectible Saturnus iconSaturnus is recommended since the tears created by it don't count as a miss if they fall to the floor. However, enemy tears that get in the ring do count as misses when they fall.
  • Collectible Rubber Cement iconRubber Cement combined with (in Afterbirth † and Repentance)Collectible Lachryphagy iconLachryphagy makes it so that Judas can't be damaged by his own tears at all.
  • Collectible Continuum iconContinuum combined with Collectible Proptosis iconProptosis makes it so that Judas can't be damaged by his own tears at all.

Bad Items[ | ]

  • Taking Collectible Tammy's Head iconTammy's Head or (except in Repentance) Collectible Sad Bombs iconSad Bombs is not recommended, as they release tears which all count towards hit/miss. Since they release multiple tears at a time, they will almost unavoidably cause tears to hit the ground.
    • (in Repentance) Tears released from Tammy's Head or Sad Bombs no longer count as misses or hits.
    • Collectible Isaac's Tears iconIsaac's Tears, however, don't.
    • The Collectible Tear Detonator iconTear Detonator doesn't count either.
  • Unless Judas already has piercing tears, Collectible Lost Contact iconLost Contact should generally be avoided. While blocking a shot does count as a hit, without piercing, it will also destroy the tear before it can do any damage, making bullet-heavy fights such as Boss Mom's Heart ingameMom's Heart/ Boss It Lives ingameIt Lives and Boss Isaac ingameIsaac extraordinarily difficult.
  • Shots fired by the familiar with Collectible Incubus iconIncubus will damage the player.
  • Taking any item that multiplies the number of tears (e.g. Collectible 20 20 icon20/20, Collectible The Inner Eye iconThe Inner Eye, Collectible Mutant Spider iconMutant Spider, or Collectible Monstro's Lung iconMonstro's Lung is not recommended, as Judas has to hit with every tear to not take damage.
    • Similarly, taking Collectible Multidimensional Baby iconMultidimensional Baby, (in Afterbirth † and Repentance)Collectible Compound Fracture iconCompound Fracture, Collectible Cricket's Body iconCricket's Body, Collectible The Parasite iconThe Parasite is not recommended, as the split tears also have to hit enemies for the player to not take damage.
    • Be careful picking up too many familiars, as picking up 3 will transform Judas into Conjoined, which will make him shoot 2 additional tears at an angle and damage Judas if they miss.
    • (in Afterbirth † and Repentance) Be careful when picking up any active Book items, as picking up 3 will transform Judas into a Bookworm, periodically giving him 2 shots.
  • Collectible Godhead iconGodhead can be dangerous, as even if the aura kills an enemy, if the shot doesn't hit an enemy or poop, it will count as a miss.
  • When using Collectible Maw Of The Void iconMaw Of The Void, keep some distance against non-boss enemies. If the ring kills an enemy before the tear hits it, it can cause Judas to miss the shot.
  • Collectible Circle of Protection iconCircle of Protection: Judas can take damage from tears reflected by the ring.
  • Collectible Explosivo iconExplosivo should be avoided. The Explosivo shot doesn't count as hitting the enemy until it blows up. If Judas kills an enemy with the Explosivo shot on them, the tear will fall to the ground and will damage him. Enemies that jump or teleport will also cause Explosivo shots to fall off. If the enemy with an Explosivo shot walks near a wall, the tear will disappear and will cause damage.
    • (in Repentance) Non-exploded Explosivo tears that fall to the ground no longer cause damage. Explosivo is a valuable damage upgrade now.
  • Collectible Soy Milk iconSoy Milk is not recommended, as it prevents charging shots (instead, firing automatically like regular tears). Judas does get a +1 damage increase after the damage reduction but the fast fire rate will make it nearly impossible to stop tears hitting anything other than an enemy.
    • (in Repentance)Collectible Almond Milk iconAlmond Milk similarly prevents charging shots and adds an unpredictable worm effect
  • Taking Collectible The Wiz iconThe Wiz is not recommended, as firing two tears simultaneously will almost certainly cause one tear to miss.
  • Taking Collectible My Reflection iconMy Reflection is not recommended, as firing a tear from a long distance causes the tear to reverse back the opposite direction and miss unless there is an enemy behind Judas.
  • Hitting a target while having Collectible Cursed Eye iconCursed Eye still damages and teleports out of the room.
    • Charging shots before entering a room can kill, since it will fire a big tear followed by 3 little tears, causing damage.
  • Collectible 3 Dollar Bill icon3 Dollar Bill, Collectible Fruit Cake iconFruit Cake, and Rainbow WormRainbow Worm are not recommended because the changing effects will make it more likely for tears to miss.
  • Collectible Libra iconLibra will balance stats, making Judas' damage much less effective and thus necessitating more shots.
  • Collectible Bob's Rotten Head iconBob's Rotten Head will harm Judas if it fails to connect, so it is not recommended unless used for combat.
  • Using (in Afterbirth † and Repentance)Collectible Clicker iconClicker may take away Collectible Chocolate Milk iconChocolate Milk, making the run significantly more difficult.
    • However, if using Clicker results in becoming Lilith, the challenge becomes much easier (see Incubus under Good Items).
  • The instant kill effect of (in Afterbirth † and Repentance)Collectible Little Horn iconLittle Horn doesn't count as a hit, and will hurt Judas.
  • (in Afterbirth † and Repentance)Collectible Trisagion iconTrisagion will cause Judas to take damage on every shot.
  • (in Afterbirth † and Repentance)Collectible Flat Stone iconFlat Stone will cause Judas to take damage on every tear's skip unless the tear hits an enemy before the next bounce.
  • (in Afterbirth † and Repentance)Collectible Ghost Pepper iconGhost Pepper will deal damage to Judas each time the blue flame spawns.
  • (in Repentance)Collectible Twisted Pair iconTwisted Pair is not recommended, as tears from each familiar count as needing to land or else Judas will take damage.
  • (in Repentance)Collectible Urn of Souls iconUrn of Souls will harm Judas for each full shot fired.
  • (in Repentance)Collectible Revelation iconRevelation is likely to kill any basic enemy it hits before the Chocolate Milk shot reaches it, making it difficult to avoid damage when firing charged shots.
  • (in Repentance)Collectible Neptunus iconNeptunus fires many shots at once, making it very easy for the player to shoot more than needed and cause self damage.
  • (in Repentance)Collectible Spirit Sword iconSpirit Sword in combination with (in Repentance)Collectible C Section iconC Section will cause the babies to fire beams in random directions that cause self damage if said beams don't hit an enemy before landing.
  • (in Repentance)Collectible Strawman iconStrawman is basically useless, as The Keeper's tears will also damage themself (Not Judas), essentially killing themself in a few seconds due to The Keeper firing automatically while Judas charges up Chocolate Milk.
  • (in Repentance)Collectible Eye of the Occult iconEye of the Occult will generally make it harder to control your tears and will probably result in a failed run.

Reward[ | ]

Trivia[ | ]

  • The challenge's name, "Onan's Streak," and the challenge conditions are a reference to the biblical character Onan, the son of Judah. According to Old Testament law, a man with a married, deceased brother would have the responsibility of producing an heir for his sibling. Onan knew that having this heir would prevent him from legally owning his brother's land, and so spilled his semen onto the ground. God viewed this deed as wicked and killed Onan.
  • (except in Repentance) Despite the challenge starring Character Judas iconJudas, the challenge is only unlocked when beating Boss Mom ingameMom.

Bugs[ | ]

Bug Bug! If Judas misses a tear and picks up the trophy while getting hit, he will be frozen in position. Going to the main menu and continuing the run solves this.
