It is when you only have one health and you have to restart the room. It is literally "9 Chances to clear out a room without getting hit" Which when it comes to facing the heart, near impossible.

Curse of the Blind?

Curse of the Blind isn't bad, only forces you to use memory which isn't that hard.

It's not actually too bad though if you're like Azazel. Chances are you won't even lose a life because 1 health isn't bad when you have 11 evil hearts. If you pick up dead cat when you have only one red heart, it's really good, because it's a Guppy item and has no negative consequences.

You're thinking of Curse of the Unknown, which hides your health. Curse of the Blind makes it where you can't see your items.

@Mantis Actually it's neither. I'm just stupid and mistakes it for fly hive.
Yes there are no negative effects if you only have one health, but you very rarely have only one health.

Unless you are Blue Baby, it doesn't affect Soul, Black, and Eternal Hearts. In fact, you gain a Red Heart when you pick up a dead cat in those circumstances (except, unless, you are playing as the Blue Baby).

Hell, if I have like 3 red hearts, two guppy items, and a bunch of soul hearts, I'd still grab it.

Again, it's useful in certain circumstances. But when you don't have soul hearts or black hearts it

It's pretty good, nine lives isn't bad.
