Tainted Flandre is a character in Reverie: Make Good Omissions, a mod for The Binding of Isaac.

Blood Gem (consumable slot)

100% chance for a Devil Room to spawn after beating a boss, regardless of damage taken, except on floors where Devil/Angel Rooms don't normally spawn.

The Devil Room will stay open after leaving.

Angel Rooms will never spawn.

Most enemies drop a Half Heart upon death, that will disappear after 1.5 seconds unless picked up.

Tainted Flandre will lose 4 Stress for each half a heart of self-damage taken.

The stress status bar is displayed on the HUD. Tainted Flandre starts with 100 Stress and Stress cannot exceed 100.

Tainted Flandre has different traits in different Stress states:
• If Stress > 50, have a Stress / 100 chance to gain a Broken Heart for each instance of non-self damage taken.
• If Stress ≤ 50, gain ×(100 - Stress) / 50 damage multiplier and have a (100 - Stress) / 10% chance of removing a Broken Heart after killing an enemy.

For each Broken Heart removed, spawns 1 item from the Angel Room item pool.

When Tainted Flandre has no Broken Hearts, an additional free item from the Angel Room item pool will spawn in the Devil Room.

Tainted Flandre will gain Stress under the following situations:
• Gain 1 Stress for each initially spawned enemy killed in rooms entered for the first time.
• Gain 1 Stress for each trap killed or Shopkeeper destroyed.
• Gain 1 Stress for each poop or fire place destroyed.
• Gain 0.5 Stress for each rock destroyed.
• Gain 5 Stress for each machine or beggar destroyed.
• Gain 5 Stress for each half black heart obtained.
• Gain 25 Stress for each half a heart of non-self damage taken.

All Soul Hearts gained by Tainted Flandre are converted into Black Hearts.

Tainted Flandre shares many details with her non-tainted version: she has no reflection in water, and picking up devil-related items does not cause changes in her skin tone.

The design of Tainted Flandre incorporates various dark, tragic, or psychologically intense fanon settings and storylines associated with Flandre Scarlet, such as:
• In Koishi's Heart-Thumping Adventure, Flandre Scarlet has her wings torn out by Koishi Komeiji.
• Flandre Scarlet is confined to the basement by her sister, Remilia Scarlet, who forbids her from going outside.
• Flandre Scarlet mistakenly believes her sister does not love her due to Remilia Scarlet's infrequent visits to the basement.
• Flandre Scarlet develops psychological issues as a result of being isolated in the basement for extended periods.

Although Tainted Flandre has a description labeled "Bad Kid" in the main menu, she is actually a good kid.
Her initial high luck stat (higher than that of any base game character) is designed with reference to the effect of Perfection.

Since Tainted Flandre does not wear a hat, some players have commented that she looks quite similar to Rumia.
