Twinkle of Contagion is a passive item in Fiend Folio, a mod for The Binding of Isaac.

Upon entering an uncleared room, there is a 50% chance for a random enemy to gain a twinkling yellow aura.

Getting the enemy in Isaac's cone of vision (30° or less required) will transfer the aura onto Isaac and grant him a stat boost:
×1.5 fire rate multiplier.
×1.5 damage multiplier.
+3 luck.

While Isaac is holding the aura, there's a 0.5% chance each frame (15% per second) for it to be transferred onto a random enemy.

For an enemy to be able to hold the aura, it must satisfy the following criteria:
• is not a boss.
• is not in Isaac's cone of vision.
• can be targeted.
• can have status effects.

The aura is instantly transferred if the enemy carrying it dies.

There mustn't be any obstacles between Isaac and the enemy in order to transfer the aura.

There is no range limitation required in order to take the aura from an enemy.

This item contributes towards the Spun transformation. Collecting 3 items from this set will grant Isaac +2 damage, +0.15 speed and spawn a random pill.
