Inverse Key is an unlockable active item in Godmode Achieved, a mod for The Binding of Isaac.
On useSets Isaac's Gilded chance to 0%. Whatever Isaac's Gilded chance was before this reset will dictate how strong the effects of this item are.
When used at 100% Gilded chance, removes 8 Broken Hearts and 8 Faithless Hearts from Isaac. When used at 0% chance, does not remove any.
Each 12.5% of Gilded chance removes 1 more Broken and Faithless Heart.
In addition to this reset, this item turns back into the Fractal Key and Isaac explodes.
While heldAll golden pickups are replaced with 3 random versions of that pickup (if another golden one is rolled without this bonus, this could lead to a chain reaction but the chance this item grants does not apply to this split).
The chance that this item grants will decrease by 1% for each new, uncleared room entered.
Defeat The Fallen Light as Tainted Cain.
