I just want to make a note that I don't have any actual sources to link these claims. Everything i'm stating here i've gotten from several forum people. I figured I'd do a round up of said information. Keys: Alright. Probably the most confusing part. We were all lead to believe that each difficulty would drop one key per week. However in reality we get keys entirely differently. According to the forum we all will get one key each week for "free." per character. Wether we get it from a PoE session or from the PoE vendor i'm not sure. We also get keys from the ether chests. Also several people have claimed to get keys from the 2 smaller chests at the end of PoE. So basically you get a key each week from someone, can farm keys from ether chests, and is a possible reward from the smaller chests in PoE. Loot: Now I want to start by saying I don't know if difficult has any impact on chances at loot in the big chest or if different difficulties have seperate loot tables. I'm ASSUMING they all share a basic loot table except for 35 which was already noted to have unique rewards of it's own. I think that difficulty for the most part is just increasing your odds. The exception to this being the exotic bounty "the elder cipher." So far I've only seen someone get it on the level 34 difficulty. This cipher is how you get the 3 fallen themed exotics. Meaning xur will never sell them. But other then that I believe the drop tables are the same barring level 35. Anyway, Each week you are promised 1 exotic. But you still have a chance to get more exotics from the chest. I know this because i've seen a few people report getting more then one exotic after a few runs. And that everyone seems to have gotten an exotic on their first run. Another thing to note. It seems in order to grab loot from this chest you need to use a key. Even if your friend opens it visually you still need to spend a key in order to "loot" the chest. Just as a note I'm pretty sure the fallen themed armor is not a drop in PoE. however queens armor is supposed to be. I have also not seen any radiant or ascendent materials drop. Just motes, coins, glimmer, glimmer consumable, planet materials, ammo synths, keys, PoE themed legendary weapons, queen weapons, exotics. TLDR: one key a week for sure. you can get keys in PoE and in ether chests but they are random. one exotic for sure per week. You always consume a key when looting the big chest. It is unknown what is the difference loot wise between all the difficulties. But it's assumed that 35 has unique rewards and the exotic bounty only drops from the higher difficulties.
