Here's a little something that could be useful to those of you who are planning to homebrew your own encounters and adventures for the 5e playtest: a list of monsters by XP value and a list of magic items by rarity.
I'm also attaching a pdf file with better formatting.
I hope you find this to be helpful! :)
