I'm trying to make a tanky spark build in path of building that I can use as a base to start making a build in game. I haven't tried to make my own build from scratch before and i've got to a point where I'm not sure what else I can add without adding a lot of expense. I'd like to keep any crafting of items cheap/deterministic. The goal of the build is to make a budget "siege mode inquisitor". Any help on ways to improve are much appreciated.
