This is a really nice gesture! I already have the rules and the Frostgrave Folio, but I forwarded the offer on to a friend who I had recently introduced to the game. Now he has his own copy of the rules and a solo campaign to keep himself busy with.
Seeing the offer also made me think that the Dark Alchemy cooperative campaign might be a way to get a game or two in with my young son while games with our usual group (with whom we are playing through the Thaw of the Lich Lord Campaign) are suspended. We picked new level 0 wizards (each from a school of magic we had not used before) and assembled warbands using a fairly random assortment of miniatures from our collection. We then played a game on the kitchen table:
I took my new Sigilist Wizard (he is not quite finished, but good enough for a game), along with a Thief and a Musketeer (using the stats from the Spellcaster magazine).
For the "Alchemical Monstrosity" we used a figure sculpted by my six year old daughter. I don't think she was offended.
My son's warband hacked their way through waves of giant rats, whereas mine was cornered by the Monstrosity. My Thief's dagger proved rather inadequate and he was squashed.
The Monstrosity was eventually felled by the Musketeer and Dr Octopus escaped with one treasure (and one health point!), while my son made off with the other three. It was good fun, the reduced number of models meant the game moved quickly and kept my son's attention. We will play the next game in the campaign next weekend. Definitely recommended to others!
