SummaryOpenForge 2.0 The cut-stone arrow slit helps you build defensive fortifications, be it a fortress, dungeon entrance or a castle. OpenForge is now a patron supported project. I use the resources that my patrons give me in order to get the resources to let me create more sophisticated tiles with a greater level of detail. Please, support me, and I’ll deliver an ongoing stream of awesome gaming terrain.Post-PrintingInstructionsFor assembly instructions, painting videos and other extra information, see the instructions on the cut-stone wall.
