Tainted Magdalene

Tainted Magdalene is a character added in The Binding of Isaac: Repentance. She is the alternate version of. Tainted Magdalene is unlocked by reaching and using either the  or the  to access a special room in one of the walls while playing as Magdalene.

Tainted Magdalene starts with 2 heart containers, 2 empty heart containers, and in the consumable slot.

When Tainted Magdalene's health is above 2 red hearts, she will leave red creep on the floor and will lose health at the rate of half a heart per 10 seconds. This health loss affects all types of hearts, but prioritizes red heart health, and the affected hearts on the health bar are faded and slowly pulsating. Bone hearts are drained, but empty bone hearts will not break. She also receives double healing from all sources except heart pickups, and all enemies have a chance of dropping a half red heart upon death which will flicker and disappear in 2 seconds. Additionally, all the leaking hearts, including red ones, will protect against loss of Devil deal chances: only non-leaky red heart damage will impose a penalty.

The first two red hearts as well as rotten hearts are the only hearts that can not leak. When Tainted Magdalene only has soul hearts, they will still leak, until she has half a soul heart left.

Tainted Magdalene has a unique melee "hug" attack which is automatically performed on enemies who make contact with her, performing a swing similar to which can synergize with any held items. The melee hits deal 6x damage. Enemies killed by the melee attack will always drop a half red heart.

Strategy
Tainted Magdalene draws her power from having very expendable health early game. Her ability to regenerate hearts from slain foes allows for simply charging into groups of enemies and killing them all with her unique hug attack, whilst not only being able to sustain her health from the dropped hearts, but actually gaining health since the hearts will also drop while she has invincibility frames. This can result in massive health gain from large groups of one-shottable enemies. These advantages come at the cost of her base damage, which is significantly lower than other characters at a permanent 0.75x multiplier. Items that especially increase damage should be a priority early on, so that she may remain effective later in the run.

It should be noted that soul hearts and black hearts will drain just like red hearts do, so they are much less useful on Tainted Magdalene. Her leaky red hearts protect against the loss of a Devil deal too, meaning soul hearts and black hearts serve even less of a use.

Whilst she excels against groups of weak enemies, Tainted Magdalene suffers against bosses that don't summon many enemies, such as Delirium. Unless she can find a way to sustain her health pool for the fight (with items such as combined with her ) she will slowly lose health until she is down to her permanent 2 red hearts, which can be risky to fight bosses with. Items that provide health such as are extremely useful for these fights.

Curse of the Unknown can cause more trouble for Tainted Magdalene than for other characters, as knowing how much health she has is important. She stops producing red creep when low on health, which may be useful as an indicator.

Good items

 * Items that grant invulnerability or shield: Melee attack can be used without taking contact damage.
 * Items that grant a damaging familiar such as or, as they can greatly increase melee damage output. Keep in mind however that enemies killed by the familiars do not have the guaranteed half-heart drop.
 * Items that triggers when getting hit, such as, , or , are likely to trigger quite frequently due to Tainted Magdalene's playstyle, making her benefits from those items much more than other characters.
 * Greatly improves longevity in long boss fights by allowing repeated usage of Yum Heart.
 * : Gives more damage the more empty heart containers Tainted Magdalene has. Due to them draining naturally, this is an excellent item for bosses.
 * : Taking damage triggers a ring around Tainted Magdalene that deals rapid tear damage to everything it touches. Good for bosses.
 * Running fast enough will allow the hug attack to be used without taking damage.
 * Removes the chance of Curse of the Unknown, as well as other curses.
 * Blind Rage: Increased length of invincibility frames allows getting in more melee attacks from a single hit.
 * Can be used to gain huge amounts of damage and speed, while being able to heal back up quickly. Can be quite dangerous for the first few rooms however.
 * : Provides another non-leaky red heart, for a total of three.
 * Note: This moves the threshold of what counts as true damage when accounting for Devil and Angel Room spawns as well.
 * The rainbow poop that spawns will be destroyed by the melee attack, refilling all red heart containers. With many heart containers, this effect will trigger often.
 * : Gives small stat boosts whenever red hearts are picked up, allowing a steady stream of stat increases while destroying enemies.
 * / : Kills heal for double the amount.
 * The damage increase is guaranteed because the melee attack does not miss.
 * Equality!: Doubled hearts do not vanish like the half-hearts they replace.
 * : Magdalene's tendency to receive damage keeps the Minisaac count high.
 * : Drops extra non-disappearing half red hearts when enemies are killed and grants a chance to receive soul hearts when hit.
 * The hug attack can be used without losing invincibility.
 * : Gives a Yum Heart charge while using the melee attack, for more sustainability.
 * With Habit and, Tainted Magdalene is essentially immortal, as it takes two hearts to charge Yum Heart, the same amount it heals for.
 * Likewise, Habit and also provides a measure of immortality, as it takes up to four hearts to charge Yum Heart, the same amount it heals for. This strategy does require having a high enough maximum health cap, however.
 * : Can be used to create explosions during the melee attack at no additional health cost.
 * : Spawns angelic familiars after picking up a certain amount of hearts. As Tainted Magdalene can both spawn hearts and drains them naturally it is very easy to quickly gain familiars from this item.
 * : Insanely powerful for Tainted Magdalene as it removes contact damage for her body, making it so she can constantly do her melee attack with no consequences.
 * : Taking damage triggers a burst of tears and increases fire rate for the rest of the room.
 * : The disappearing half red hearts can be stored in the Jar. When emptied out, the spawned hearts are permanent.
 * : A charge is granted every time the melee attack is used.
 * Lost Cork: Significantly increases the size of the creep Tainted Magdalene frequently produces.
 * : Dropped half hearts heal for one full heart.
 * : Dropped half hearts are drawn to Tainted Magdalene, making them easier to retrieve.
 * : Multiplying enemies into weaker versions of themselves makes the melee ability more viable and generates more hearts to replenish HP.
 * If Tainted Maggy gets any effect that spawns monsters in immense numbers she can get immortality, as long as she kills spawned monsters and pick ups health.
 * : Petrifies and damages enemies on touch, and the coins spawned when they are killed further increase the touch damage.
 * Mom's Locket: Dropped half hearts will be converted to full hearts.
 * / : Hearts have a chance to drop every time damage is taken from doing the melee attack, and they won't disappear shortly after spawning.
 * The lethal hug ability does not cancel the paused state unlike firing tears.
 * : Explosions heal for one full red heart.
 * : Coming in contact with enemies will poison them. Poisoned enemies have a chance to drop black hearts.
 * : Since it takes two hearts to charge and Yum Heart grants 2 full red hearts when used, it can be used infinitely without losing HP. Doing this will also prevent HP to decay while doing this infinite combo. Additionally, the Invincibility-frames from the damage taken last long enough to become permanently immune to any other damage source. Tears can't be fired while doing this, but it is still possible to kill enemies with Tainted Magdalene's melee ability, basically guaranteeing a win on the spot. Binding the "use pill" key to a more accessible key, or plugging in a controller, to move around easier is recommended. This also counts as taking damage, meaning items that cause an effect upon taking damage (such as Piggy Bank or Cracked Orb) or reaching a certain health threshold (such as The Negative and The Polaroid's half heart threshold) can be repeatedly activated to gain their benefits.
 * + : Allows for infinite red health regeneration.
 * + : Essentially allows an on-demand charge-free, which pairs greatly with Tainted Magdalene's hug attack.
 * + 9 Volt: Repeatedly pressing the activation key will allow for infinite health, invincibility frames and charge for other activated items.
 * 's swings can collect the red hearts dropped by enemies, making it significantly easier to heal. Additionally, it's effectively a strict upgrade to the hug attack, as it has similar damage output without the requirement to take damage to use it.
 * : Takes a while to charge, but provides invulnerability and lots of melee damage.
 * : Tainted Magdalene will still perform melee attacks while this is active.
 * : Taking damage triggers a burst of tears that deals very high damage.
 * : Tainted Magdalene's tendency to receive damage keeps the amount of spirits high.


 * Allows Tainted Magdalene to trade her plentiful red health for coins.
 * When combined with, allows Tainted Magdalene to farm infinite coins by refilling her Yum Heart.

Bad Items

 * will make it more difficult to hit enemies since they will become feared upon getting near them.
 * will remove all red heart containers, replacing them with black hearts. The black hearts will slowly deplete over time and are hard to replenish.
 * is very rarely active, as red hearts are hard to keep full.
 * is frequently inactive, as builds with only one red heart are difficult to keep up and survive.
 * can pay out more often, but the black hearts he drops are much less useful. He will also take red hearts that may be needed for healing.
 * is not recommended, as it reduces red hearts to one. Replacing them with soul hearts to compensate is also more difficult and harder to sustain.
 * will take priority over the hug attack, meaning it will make the enemy turn into a poop, without providing the half red heart.
 * will instantly be exploded by Tainted Magdalene's swing, doing an explosions worth of damage.
 * is not active very often.
 * will deal contact damage to enemies, occasionally killing enemies before the hug attack does, without providing the half red heart.
 * is not recommended, because it will make taking hearts or any other pickup considerably more difficult.
 * is essentially useless as it will almost always die moments into the floor because of how Tainted Maggie plays.
 * Apple of Sodom will sometimes transform red hearts into blue spiders, limiting health regeneration.
