After some serious exploration and further runs on PTR and live, I think I have come up with a much more reliable large gold chest route than from my first video. I managed to snag 16 chests myself in one run!
Of course, RNG is RNG. Incredibly, if it was good RNG I could've gotten as many as 20 or 21. I recommend listening to my audio commentary as well since I noob it a couple of times in the vid.
GOOD LUCK everyone! Post back how many chests you get!
EDIT: I should also add that BE CAREFUL ON USING ELDERS CHARM ITEMS (key, sleep powder, etc). If you are going to use these items, you must use them OUT OF COMBAT. If you use one in combat all items go on a 1 min CD, and when you fall out of combat, another min is added, so technically 2 min CD if you use an item in combat. Be careful. You can use as many as you want with like a 5 sec CD or so between each one as long as you stay out of combat.
