Pit fiend hearts, used to create three greater fire essences. They now create 1 each. This means they're the same as greater fire snake glands, which also create 1 greater essence each, but have a lower DC.
Gelugon hearts, used to create 1 greater icy essence each, now they create 1 greater icy essence per 3 hearts. This means they are the same recipe as hearts of the entombed, but with a higher DC.
