D&D 5E Rats of Waterdeep, new adept program adventure at DMSGuild, not "yet" legal for AL?

[darjr]

Love Waterdeep! I wan't more of it in 5e. Just purchased this but haven't read it yet. It's been a little bit since the last guild adept release. I'll try and review it when I read and play it some time hopefully soon. I also hope it, at least in part, becomes AL content. The link below is my affiliate link.
