Burning	-	Can absorb one fire or explosive damage before turning into a pure heart.
Spiked	-	Can absorb one spike damage before turning into a pure heart. Caution: this heart will replace one of your other hearts and can kill you if you have only one heart that isn't spiked!
Lucky	Yes	Enemies will give better hearts and more gold. Crits percentage will raise. More lucky hearts you have = more effect.

Broken	No	No added effect. Similar to Pure heart.
Cheating	No	Allows player to break regular doors. Only appears in shops. To cheat, you should go to the left door.
Glitch	No	Warps the player to the room opposite of the current number. Is obtained after Cheating has been used on room YX. It will appear in a chest, and when you exit the room, warps you to room XY, (eg, use the cheating heart on room 19, gives you a room 91 glitch heart warp). Warning: This can cause a jumpscare. Obtaining this makes your hearts flash quickly in different colors and display a bunch of error messages and random text on your screen.
