The quests look simple enough for most DMs to accomplish a large percentage of them.
Although there does seem to be a file missing. The Initiate quest references the Curse of Strahd DMs Packet being on DMsG, but I don't see it there as of this post. I would imagine that it's probably in the process of being uploaded right now, so that's not a major concern.
I also noticed that two of the quests don't have listed rewards: Ritual of Scrying and First Timer. I assume that this was a typo, as the rest of the document uses the word "None" where there are no rewards to be obtained.
Also, I think we could probably use a little guidance as to the start date for completing quests. Even though this just came out today, I would assume that any quests that you have completed since the start of the season (March 4th) should count.
EDIT: When it says that you can obtain a magic item that is tier-appropriate, can it be of a lower rarity than what's listed for your tier? For example, would I only be allowed to give Rare items to my Tier 2 character, or could I give Uncommon items as well?
