The Node Fabricator will not add new aspects to a node. It will recharge aspects that a node already have very quickly using essentia. This is potentially useful for frequently used wand recharge stations. It will also consume the essentia even if it doesn't need to, so blowing through 14 jars of Terra doesn't surprise me at all. I am currently making some updates to the Node Fabricator and have updated it so that it will not consume essentia it doesn't use. I have also been toying with the idea of enhancing it so that it can add new aspects to a node. I might do this, but make it extremely expensive as it is a very powerful addition.
