The following answer is taken from a question I posted in Arqade here. The question was regarding the contents of Iron Lockboxes.
Gives random accesories, shadow keys (lots of them) , Cool Wolver Tail, and other stuffs which in that case are rare.
The thing that surprised me the most is that he copied his answer directly from the Spiral Knights forums without citing them.
Comparing his answer with the Forums answer, linked here:
Gives a random cosmetic accesory. It's like gambling, 90% of the time, like shoebox says it's useless.
Yep. Got a Cool Wolver Tail on my first lockbox :3
As for what is inside of the boxes...
Accessories, and shadow keys. That is all. (and your chances of getting anything good are slim.)
Essentially, he took his answer from the forum, without linking them or citing them. Not to mention his answer was extremely vague. Is this behavior acceptable? Should answers be cited?
