I've been DM:ing a campaign weekly since march last year, and the characters are lvl 9.
The players are amazing with a focus on roleplaying and social pillar with lots of intrigue. They have just found a Spelljammer helm, met with a representative for The Arcane, and converted a galleon from Waterdeep navy for jammin'. They have a level or two left on Toril resolve, then off to Braals Rock it is, to hopefully save Realmspace from undead Illithids and their unknown masters!
Much fun is had, so I hope we can take this all the way to lvl 20.
