Binding of Isaac: Rebirth Wiki

Suicide King is Challenge #7. Character Lazarus iconLazarus is the default character for this challenge, and he starts with Collectible Ipecac iconIpecac, Collectible Mr. Mega iconMr. Mega and Collectible My Reflection iconMy Reflection, as well as a random pill. The goal is to defeat Boss Isaac ingameIsaac. This Challenge is unlocked once Boss It Lives ingameIt Lives and Character Lazarus iconLazarus are unlocked.

Difficulty[ | ]

  • Though Ipecac and Mr. Mega would be a powerful build in a normal run, My Reflection causes tears to loop back around towards Character Lazarus iconLazarus, forcing him to have to avoid not only enemy tears but his own as well. This also makes aiming tears significantly harder.

Strategy[ | ]

  • The 1 pip and 6 pip dice rooms will not reroll the starting items for this challenge but will reroll any others.
  • Lazarus has one extra life by default, granting him some survivability.
    • (in Repentance) Character Lazarus Risen iconLazarus Risen now regains his extra life and reverts back to Character Lazarus iconLazarus upon entering a new floor, thus allowing for more survivability.
  • Due to My Reflection, the range is diminished. With a little practice, however, it can be easy to tell how far away the shot will travel. Lining up enemies with that distance will make it easier to score direct hits that won't come back. One way to track this is by the shadow of the Ipecac tear.
  • Ipecac's explosive tears can be used to break rocks, mushrooms, and skulls, and open secret rooms.
  • Crawl SpaceCrawl Spaces are very valuable due to the lack of Treasure RoomTreasure Rooms, making the destruction of all encountered rocks a viable strategy. Most items that can be acquired this way are useful, but Collectible Pyromaniac iconPyromaniac and (except in Rebirth)Collectible Host Hat iconHost Hat are especially noteworthy for their ability to prevent all self-damage inflicted on Lazarus.
    • Collectible Gnawed Leaf iconGnawed Leaf allows Lazarus to turn into a statue just before the Ipecac tears hit him. This is only really useful for destroying objects.
    • While Collectible Dr. Fetus iconDr. Fetus will not prevent any damage inflicted by bombs, it is more controllable than ipecac shots.
      • (in Repentance)Collectible Dr. Fetus iconDr. Fetus now prevents self damage from ipecac.
  • Familiars such as Collectible Cube of Meat iconCube of Meat, Collectible Ball of Bandages iconBall of Bandages, or any friendly fly orbital can help protect Lazarus.
    • If properly aiming the Ipecac shots while simultaneously dodging them proves too challenging, some familiars or orbitals can serve as a consistent means of dealing damage without firing tears.
  • Grouping enemies together is an effective way of clearing rooms while minimizing the amount of tears needing to be fired per room.
  • Because Ipecac also increases the damage of Blue Flies and Blue Spiders, obtaining an item that spawns them can be extremely useful.
  • It is possible to hit enemies without having to worry about My Reflection by moving in tandem with the Ipecac tear, making the shot faster. This method only works with a high Speed stat.
  • A higher Shot Speed stat allows the tears to fly further away from Lazarus before returning, allowing enemies to be shot from further away while reducing the risk of being caught in the blast radius.
  • A lower Range stat is advantageous. It shortens the way back to Lazarus whereas a high Range stat seems to home him.
  • The Collectible Magic Fingers iconMagic Fingers item is a common shop item that is affected by Ipecac's damage increase. This makes it extremely viable as an alternative damage source to Ipecac tears, especially in runs with a large coin count.
  • If EnvyEnvy is encountered, and it drops Collectible Shoop da Whoop! iconShoop da Whoop!, it is highly advised to pick it up. Due to the item's relatively quick recharge time, and the fact that its damage is greatly increased by Ipecac, it can be used as an ace in the hole to clear challenging rooms and easily defeat bosses.
  • Collectible Mom's Knife iconMom's Knife can be purchased from a Devil RoomDevil Room if found with a Red Chest or using Collectible Goat Head iconGoat Head, overriding Ipecac and making the challenge much easier.
  • Collectible Death's Touch iconDeath's Touch makes tears much bigger and allows the tears to do damage in-flight, making it significantly easier to hit enemies.
  • Collectible Technology iconTechnology is an immensely useful item that can be acquired from Boss RushBoss Rush, as it overrides Ipecac, granting infinite range and no explosive damage.
    • (in Repentance)Technology now grants explosive damage. As it behaves unpredictably with My Reflection; it is not advised to pick it up.
  • (except in Rebirth)Collectible Tech X iconTech X is also useful, because it overrides My Reflection while keeping the explosive damage from Ipecac. This is especially good on large enemies that might take multiple hits (and thus, explosions) from Tech X.
  • (except in Rebirth)Collectible Succubus iconSuccubus is an incredibly useful familiar, as its damage scales with Lazarus'. Succubus allows the challenge to be cleared without using tears as it only takes a few seconds for it to clear out a regular-sized room autonomously.
  • (except in Rebirth) Familiars that mimic Lazarus' tears, such as (except in Rebirth)Collectible Fate's Reward iconFate's Reward, are not recommended for this challenge. While they do increase Lazarus' overall damage output, they are very difficult to avoid, as they are usually fired directly towards Lazarus.
  • (in Repentance)Collectible Spirit Sword iconSpirit Sword overrides the explosive projectiles from Ipecac if Lazarus is not at full health, making self-damage far less likely at the cost of making Lazarus into a close-range fighter.
  • (in Repentance)Collectible Brimstone iconBrimstone and (in Repentance)Collectible Sulfur iconSulfur are extremely useful for clearing rooms and has an absurd synergy with worm trinkets.
  • (in Repentance)Collectible Eye of the Occult iconEye of the Occult makes your ipecac shots more controllable.
  • (in Repentance)Collectible Sharp Key iconSharp Key can fire a damage-boosted Ipecac shot with great accuracy, and with enough keys, can be rapidly used for mass damage.
  • (in Repentance)Brain WormBrain Worm, Hook WormHook Worm and Whip WormWhip Worm are useful trinkets and should be collected if possible.
    • Brain Worm forces some tears to snap 90 degrees to target enemies that they may have missed.
    • Hook Worm allows tears to hit enemies more easily, while also making them easier to avoid by Lazarus.
    • Whip Worm forces tears to fly very fast and low, usually preventing enemies from dodging them. It also makes tears that hit the edge of the screen explode rather than coming back to Lazarus.
    • Ring WormRing Worm is a somewhat less useful alternative.
  • (in Afterbirth † and Repentance)Collectible Euthanasia iconEuthanasia or any items that fires extra shots are not recommended.

Unlockable Achievements[ | ]

Notes[ | ]

  • The Devil RoomDevil Room at the end of the Boss It Lives ingameIt Lives boss fight will contain regular Deals with the Devil instead of a trap door, as the challenge requires Lazarus to go to the CathedralCathedral.
  • If the player somehow manages to end up going to SheolSheol instead of CathedralCathedral (i.e. through a trapdoor in WombWomb II), defeating Boss Satan ingameSatan will successfully finish the challenge and unlock the achievement.
