The chest in Sanctuary? Use the infinite gold key usage on the trainer to continuously loot the chest.
That's all you need to do. And your good to go.
Sorry to hijack, but I have similar question. I used the 'add XP' option on the trainer to boost myself up to level 20, so the golden chest would release elemental weapons that I needed to complete the weapons training in Sanctuary.
Now, everyone still seems to be dropping weapons & chests seem to only have thing equivalent to what I was getting when I started boosting at about level 9/10. Is that normal?
Golden chest gives accordingly to level and i believe skills&stats also have a impact on weapon stats, level of char = 50,all skills maxxed, and stats 100%, so when at that level you get something like this, which the golden chest dropped,after several open and close sessions with the chest
