In a recently started game, our party finds itself in the position of building a village from scratch. We have a location with plenty of natural materials, currently abundant food, but that will change as winter arrives, and more labor forces than we initially expected. The job will get done.
As a low level Artificer I thought to myself, "I'll whip up an item or spell real quick to hurry things along." Imagine my surprise when I couldn't find anything particularly useful at lower levels. Higher levels are gravy, ridiculously simple.
So to be specific, we are playing Pathfinder, and the Artificer I'm using came from Adamant Entertainment. It's posted up on the srd. Third party materials are fine, if they can be found. The GM has agreed that if we can't find published spells that are useful, we'll make something up and add it to the big book of houserules, so ideas for spells would be cool too.
