Strategy[ | ]

  • When playing on a controller, The Forgotten's throw distance can be altered by tilting the shoot (right) stick at a lower angle. Useful for closer enemies and for better aim.
  • While it requires a lot of patience, a viable strategy is to restart until a Mini-Boss RoomMini-Boss Room with LustLust is encountered and that it drops Collectible The Virus iconThe Virus. It will dramatically increase the amount of contact damage inflicted when throwing The Forgotten, making it much easier to attack quick or regenerative enemies. As a weaker alternative, obtaining Collectible Mom's Heels iconMom's Heels from a Boss RoomBoss Room will work as well.
  • Obtaining Collectible Serpent's Kiss iconSerpent's Kiss makes this challenge trivial, as contact with The Forgotten will apply poison damage and cause the enemies to drop black hearts on death, effectively giving you infinite health.
    • Collectible Chaos iconChaos will be necessary to use this method, due to the fact that it is impossible to find a Treasure RoomTreasure Room in this challenge.
  • While it does require some luck, visiting shops in possibility of Collectible Birthright iconBirthright and Collectible The Battery iconThe Battery/Collectible Car Battery iconCar Battery can grant invincibility in rooms while leading the bomb to enemies.
  • It's recommended to visit as many Curse RoomCurse Rooms as possible. Tainted Forgotten can enter and exit them without taking any damage, and they can provide precious soul heart health and powerful items such as Collectible Gimpy iconGimpy and Collectible Red Key iconRed Key.
    • Hence finding or buying Collectible Voodoo Head iconVoodoo Head is a good help in this challenge.
  • It's also beneficial to bomb any Blue Fire PlaceBlue Fire Places or Purple Fire PlacePurple Fire Places the player comes across to gain as much soul heart health as possible.
  • The Forgotten will move slightly every time it explodes, unless the character has an item that grants flight. Using XII - The Hanged ManXII - The Hanged Man could prove useful for keeping The Forgotten in one spot for a room.
  • Picking up Collectible Gnawed Leaf iconGnawed Leaf is an instant win, as just holding Tainted Forgotten will provide permanent invincibility and free reign over where explosions occur.
    • Collectible Chaos iconChaos or Crawl Spaces will be necessary to use this method, due to the fact that it is impossible to find a Treasure RoomTreasure Room in this challenge.
  • Items that provide invincibility (such as Collectible Book of Shadows iconBook of Shadows) or invulnerability to explosions (such as Collectible Pyromaniac iconPyromaniac and Collectible Host Hat iconHost Hat) are very powerful in this challenge, especially when combined with orbitals such as Collectible Sacrificial Dagger iconSacrificial Dagger. Not only do they nullify self damage, they allow Tainted Soul to safely carry Tainted Forgotten as it is exploding, greatly increasing the player's control over where explosions occur. Take caution if there isn't full invincibility, though, since Tainted Forgotten's explosions can still push Tainted Soul while being carried, which could push them into enemies that survive the explosion.
  • Room clearing items such as Collectible The Necronomicon iconThe Necronomicon and Collectible Flush! iconFlush! can be useful for skipping rooms that would otherwise be difficult with Tainted Forgotten's mechanics, such as rooms with lots of fast enemies. In addition, Collectible The Negative iconThe Negative will trigger every time Tainted Soul takes damage, providing a good room clearing effect for the later stages of the challenge, though this should not be relied on too much due to the health cost.
  • The timer for Tainted Forgotten's explosion resets every time a consumable is picked up or an active item is used. This can be used to avoid taking damage in certain situations. Items such as Collectible Converter iconConverter, Collectible Sharp Key iconSharp Key, Collectible Mom's Bracelet iconMom's Bracelet, Collectible Friendly Ball iconFriendly Ball, and Collectible Bob's Rotten Head iconBob's Rotten Head can be used to infinitely reset the explosion timer.
  • Since some bomb modifiers affect Tainted Forgotten's explosions, playing the Bomb BumBomb Bum can be quite powerful. Getting Collectible Blood Bombs iconBlood Bombs, Collectible Brimstone Bombs iconBrimstone Bombs, Collectible Mr. Mega iconMr. Mega, or Collectible Sad Bombs iconSad Bombs can be quite helpful as it will greatly boost the damage inflicted by Tainted Forgotten's explosions. Collectible Glitter Bombs iconGlitter Bombs will be triggered with Tainted Forgotten's explosions, allowing to generate infinite pickups. Collectible Bomber Boy iconBomber Boy, though, while boosting the damage, will also make dodging the explosions more difficult.
  • It is better to avoid Collectible Butt Bombs iconButt Bombs. This item can help a lot if fighting small enemies, but if you encounter the Boss Brownie ingameBrownie boss, unless you can one-shot him, you will heal him with butt bombs instead. This can cause a soft lock.
  • Visiting all libraries is recommended as a Collectible Book of Revelations iconBook of Revelations will grant a lot of soul hearts and ensure that Super Meat Boy / Super Bandage Girl is obtained, which will provide the means to do damage to enemies without using The Forgotten.
  • It may be good to skip the Devil RoomDevil Room on the second floor to ensure an Angel RoomAngel Room spawns on future floors due to Character Tainted Forgotten iconTainted Forgotten being a character that can't get heart containers, making devil deals inconvenient. This will also maximize the chances of finding Collectible Monstrance iconMonstrance, an extremely powerful item for this challenge. On the other hand, the Devil Room can occasionally provide black hearts as well as Collectible Empty Vessel iconEmpty Vessel, which is also very powerful in this challenge due to its invincibility.
  • Collectible How to Jump iconHow to Jump can be used to stall the explosions of the forgotten, as the forgotten will not move and will not explode during the jump animation. Gaining flight is not advised, as it will prevent the use of How to Jump, despite regularly being usable by characters with flight.
  • Using Collectible Notched Axe iconNotched Axe will allow The Forgotten to do a melee attack. This also works as it's thrown, functioning similarly to Tainted Forgotten's regular melee attack, but without the charge attack. It also allows you to delay the explosion, as each time you use it, the explosion timer will reset.
  • Collectible Maw Of The Void iconMaw Of The Void will allow The Forgotten to do a ring attack.
  • Collectible Incubus iconIncubus will give the familiar to The Forgotten, granting you another way to deal damage more easily.
  • Collectible Twisted Pair iconTwisted Pair will allow The Forgotten to use an attack similar to the bone swing.
  • Collectible Urn of Souls iconUrn of Souls stalls the explosion indefinitely by spamming the use button to activate and deactivate. Should Tainted Forgotten also find Collectible Book of Virtues iconBook of Virtues, then he can generate infinite flames, thus removing the reliance on explosions.
  • Super MagnetSuper Magnet will pull enemies towards The Forgotten (and not The Soul), making them more likely to be hit with his explosions.
  • Collectible Revelation iconRevelation allows The Forgotten to do a ranged attack.
  • Collectible Mom's Bracelet iconMom's Bracelet allows the player to delay the explosion indefinitely, as The Forgotten will hold its arms up and reset its fuse.
  • Because Character Tainted Forgotten iconTainted Forgotten grants infinite explosion, it is recommended to destroy a maximum of obstacles to find rewards that might help. It's also a guarantee to find all Secret Rooms among other things.
  • Collectible Cursed Eye iconCursed Eye and Collectible Chocolate Milk iconChocolate Milk will not allow the player to throw Tainted Forgotten, which in most runs will lead to death.
  • Collectible The Candle iconThe Candle and Collectible Red Candle iconRed Candle are extremely helpful in this challenge, as the player will be able to stop Character Tainted Forgotten iconTainted Forgotten from detonating at any time.
  • Collectible Dad's Ring iconDad's Ring is extremely helpful due to the ring orbiting The Forgotten and not The Soul. Throwing The Forgotten at enemies petrifies them leading to easy hits with explosions. Player can also lead enemies into the ring. This combined with Second HandSecond Hand can make this challenge trivial, as petrify works on bosses.
  • Collectible White Pony iconWhite Pony allows The Forgotten to ignore the knockback from explosions making strategically placing the explosions easier.
  • Collectible The Ludovico Technique iconThe Ludovico Technique a tear follows The Forgotten as a familiar. Picking up Collectible Tiny Planet iconTiny Planet cause this tear bouncing around room.
  • Collectible Stitches iconStitches will allow you to telefrag enemies killing them instantly without changing the souls position and can also be used to put The Forgotten into specific places to bomb enemies. Activating the item however will reset the explosion timer. You cannot telefrag bosses.
  • Extension CordExtension Cord will give you another way of dealing damage. In this scenario it's better to throw The Forgotten to the other side of the room and to keep enemies between The Forgotten and The Soul.
  • Picking up Collectible Remote Detonator iconRemote Detonator does not allow you to control when the forgotten will explode. However, it can allow you to make an instant explosion wherever the forgotten is by using and immediately detonating a bomb.
  • Using any Pickups (such as cards or pills) will reset the forgottens explosion timer.
