The legendary chest seems like a great deal (even though the weapons aren't particularly my cup of tea). The skin is an interesting pick, but other than that, what are you gunning for?
Got the legendary chest for the Bolt. Turns out I need to get one gift of battle and some mystic clovers to finish my legendary. What would've cost me hundreds of gold, is going to cost me pretty much nothing.
It's awesome. Of course, subsequent legendaries won't benefit from all of my collected materials, but it's still far better than going at it from scratch.
