Craft

like a better "repair" spell, "craft" lets you take any materials to make an item you know of; such as using a 5-foot long branch to make a 5-foot long training sword, or a 3-foot cube of steel to make a shield. but in that case, if you use 2.5 cubic feet of steel instead of 3 cubic feet then the material left over is turned into a kind of ingot. so the result is a steel shield and a .5 cubic foot steel ingot. also, you have to concentrate longer for something you understand less of, like a gear; if you have the: exact specifications in mind you can make it near instantly but if you have to make a gear for a space that you don't completely understand it will take longer accordingly to how little you understand it or how complex it is.
