Now that there are a ton of new monster sets coming out soon, it is going to be super hard to get the right shoulder piece you want from undaunted chests. I am proposing that vaults are added to all of the vet dungeons that once you have 150 "keys" you can open. The keys would drop in the dungeon itself so you would have to do the dungeon to get the keys. This would essentially work the exact same way as White Gold Tower and Imperial City Prison right now. The only difference would be that the vaults would drop (or have a chance to drop) the monster shoulder piece as well. What do you guys think of this idea?
