Builder

Minor: Builder

Major: Build Master

Builder is the quick and simple little brother to Build Master. Builder can be constructed in any orientation. The Redstone block points in the "forward" direction. Builder scan any 2D template using Conductance and extrudes that template along the direction it is pointing. Right click the center block again to pause building. Builder makes heavy use of Runic Energy to produce new blocks, so make sure to feed it. Use this to rapidly increase the rate at which you can build.

Layout the floor plan for a Castle on the ground and simply extrude it up 20 meters to create the full castle. A line of red wool can turn into carpet flooring.

When laying out your build template, remember that it needs to be surrounded by air on all sides and diagonals. Unlike Runecraft or FTP, Builder can scan natural blocks like grass and stone.

Advanced Use
Builder is very forgiving about what it considers an "obstacle". Builder scans your build template and then slides that template out looking for the next place to stamp it. As long as there is at least one block that matches your template, it will not stamp the template again. This has two major effects: 1) You can break out blocks as you go and Builder will continue to build past that point.  In your castle, you'll want windows and doors that are "holes" in the template.  2) Builder can "phase" through solid objects if and only if there's at least one block that matches. So for example if you want to fill in a valley with more grass blocks, it will negotiate the ins and outs of the natural terrain until it hits a solid line with no matches (all dirt). Builder has a maximum scan range of 150 blocks (which is really far by the way).
