Wow what a painful mistake

Let me tell you a tale from this idiot.

I've been working on getting the 5 daily wins in a row for a very long time. I finally strung together 4, so this morning was it, the 5th and final win.

I load it up, it's Cain and only to Mom's Foot. This is completely doable!

I proceed through the floors, everything going great. Got a decent build, got 9 red hearts and 4 soul hearts... It's in the bag. I don't think I can lose the run from this point unless I do some truly moronic shit.

Then I see an item drop... Never seen this before. Lazarus' Soul? Oh the guy with two lives. I bet if I use this it will probably put a little 2x next to my health incase I die.

Pop it. Just straight up kills me and brings me back with only half a heart. I then proceed to die to a little turd in the next room. Streak over.
