My main build with Inkbrush that works in multiple situations is Main Saver, Cold Blooded, and Ink Res with whatever style I feel like for the day. It caught my eye that my build is essentially a mashup of several of this guide's builds, but I would never trade Ink Res for any other footwear upgrade (it pretty much negates the Inkbrush's tracking ability which can otherwise always be used as an escape option). Other than that, this guide is pretty helpful to people looking to get into brushing, and I think that's dandy. 4/5.
