diablo-3
For some reason, I am unable to find Part 2 of Leah's Journal in Diablo 3.
I usually pick up Part 1 before the people inside the inn turn into zombies, and have checked back periodically throughout my first real quest (Killing the mothers, etc.) and have had no luck finding it. I have noticed, however, that if I wait until after that quest is completed, Part 3 of her journal appears.
How do I get Part 2 of Leah's Journal?
Leah has 16 journals. They respawn in the same places in the first three acts, new journals taking the previous journal's place (so get them while you can). You can return to previous chapters if need be.
There are many lore books. You can check your book collection progress from the achievement list (press Y). Leah's journals are listed under Campaign > Acts 1-3 in the "People lore book" achievement.
It depends on the remaining damage of the killing blow.
To be exact the amount for how much is the damage of killing blow higher than the "hungry corpse" remaining life,if that remaining amount is higher than required threshold(specific number unknown for now) the "corpse" will die completely if that amount is lower it will spawn the "torso".
Simply put if the "corpse" is very low on HP and you finish him with strong special ability the chances are it will not spawn the "torso".On the opposite if the "corpse" is hard to kill (depending on your lvl,gear,difficulty...) an you just autoattack him expect him to "split".

To find Part 2 of Leah's Journal, you need to check her journal after completing the Fallen Star by talking to Captain Rumford, but before entering the Cathedral during the Legacy of Cain.
