Looks like Warriors Abyss is finally implementing that one suggestion pretty much everyone has been asking for. You'll now get a consistent King's Cauldron as a reward after the Lu Bu/Honda clone boss. Say goodbye to ending a run with like 20K tears of blood leftover because the game refuses to give you a King's Cauldron later on in your run (but it sure loves to give you one near the start when you're only like 2-3 floors in).
