8 "Useless" Video Game Items That Were Secretly GAME-BREAKERS

No, it's not just a clever name - the Cursed Skull from The Binding of Isaac is a bloody annoying item you really, really don't want in your inventory most of the time.

If you have this trinket on your person while taking damage and having less than one full red heart, you'll be immediately teleported into a random room, in turn undoing any progress you've made in the previous room up to that point.

This can prove especially infuriating during a boss fight - if you're hit by the boss and teleported out of the room, when you return it'll be back to full health, basically putting you back to square one.

But it can be exploited to effectively give the player functional immortality by combining it with the Scapular.

Y'see, when Isaac is down to his last half heart of health, the Scapular will grant him one Soul Heart.

And so, combined with the Cursed Skull, it makes the player unkillable because the Scapular gives a Soul Heart out before the Cursed Skull teleports them out of the room.

While this combo doesn't prevent the annoyance of teleportation, it does nevertheless allow you to keep playing without the threat of death for as long as you want. Just brace yourself some really, really long runs where you may or may not make progress.
