I am sorry, maybe its just me but if I go to the trouble of attaining a chest and implement a heavy duty lock I am sure as **** going to put some stuff inside that is worth a crap!
Why is it I find chests that require such skill to be nearly worthless? I unlocked one today and it had 44 gold, a wooden bowl and a iron dagger...WTF really if I didn't have the skeleton key I would have blown through at least 30 lock picks....
If its a crap chest it should be either unlocked or easy to open...just saying
You're working off the idea that all chests, in the game world, are hand chosen to have specific items, but that's not the case. Items, in chests, are random, but your current Level and Game Difficulty determines the type of content you may find.
In other words, both you and I, on different characters, go to the same exact chest, in a dungeon. You open it and find nothing, but potions. I open it and find some armor, potions, etc. That's all part of the "Randomly generated" aspect of chests.
Hope that helps make some sense of it all. RNG svcks....
