same here exept i used TBoI WOTL and i used cain and i saw 2 items they were spirit of the night and lord of the pit both were 2 hearts and i had 3 hearts and 5 soul hearts and i used the spirit of the night then i tought that if i go to the lord of the pit trade i would NOT get it but i was wrong i got lord of the pit and all my heats and my soul hearts dissapeared and i had no hearts left but when i went to the depths and got a soul heart then and died instantly to a goblin (had NO hearts exept a soul heart)
