Haven't seen this posted and hardly post myself but there seems to be a new chest spot
Start with The Royal Crypts quest
Take the TP to Cathedral Level 3
Go back to Level 2 and run down
You are looking for the room with stairs that go down normally just right down from where you enter level 2
That is where you will find the chest. It's a 50%ish so not as good as the old one but still good.
