Being the sort of person who usually prefers fighters and thieves to spellcasters in D&D-type games, I had initially not paid much attention to the latest Adventurer, Conqueror, King System* supplement to be crowdfunded by Autarch. I'm glad I finally did, though, because the magic of the Almanac of Unusual Magic is very unusual indeed.
The 56-page book covers four new ACKS classes, three of which - gnomish alchemists, dwarven geomancers, and warlords - slot in well to a fantasy milieu. The fourth, however, is the Terran Engineer - apparently riffing on a character option in Barbarian Conquerors of Kanahu* for lost spacemen who, if the illustrations are any guide, basically hail from Starfleet. The Engineer class, then, reflavors magic to be the "jury-rigging" ability of an engineer like Scotty to create fantastic devices, albeit not necessarily temporary ones. Of course, being an ACKS product, this new class (as well as the others) is broken down into its component parts for further customization, in a very Engineer-like manner now that I think of it.
Still needing about $450 to fund at the time of this writing, the GameOnTabletop campaign for the Almanac also offers an opportunity to add on ACKS rulebooks at a discounted price. I've backed an Autarch project on this platform before, and for not being Kickstarter or IndieGoGo it worked very smoothly. I highly recommend giving the pitch a look if it tweaks your interest at all.
