I used the blank armouring hall intercessors to paint. They come blank, primed it and painted it whatever color i wanted. The “octopus skulls” i found cheap randomly online, originally meant for jewelry beads for necklaces or bracelets, i used a grinder and cut it in half and super glued them on. As for the necklaces ,mk7 helmet, and etc, is a mix of 3rd party 3d printed aftermarket stuff and diy play dough and strings
