Having written the attached link, I am now very tempted to run it as a campaign. Looking for suggestions, particularly as it lacks a proper conclusion.
The format at the moment involves the party, low-mid to mid level, going on quite the trek across most of their known world to collect a set of useful, but not very powerful magics items. The quest giver wants to recombine them so they can be gifted to a granddaughter.
I'm pretty happy with the encounters for gathering each item, there lacks a conclusion or boss fight to tie it together at the end. It's possible to tweak the campaign so that the encounters becoming increasingly difficult, but I feel it really needs more of an ending than Lady Sophietta going "Well thanks, here's your reward, bye bye".
Your suggestions, Hubski, please.
