This is how the stealables that spawned in dungeons should of been set up in my opnion. U have to reveal them when they spawn and its completely random. I really think that this is a great idea and should be continued to be used in future ideas. It may be a half baked idea but i think it has a lot of merit. Makes a skill useful again and adds to the thrill of finding something that could be really rare while making it difficult to script.
