An armature is the skeleton a sculpted figure is built on: a bendable wire frame, roughly proportioned, that you pose once and then cover with putty. It solves two problems at the same time — the pose is fixed before any material is committed, and the finished figure has a core that stops thin limbs snapping. Working without one on a 25 mm figure means sculpting the pose and the volume simultaneously, which rarely survives a second attempt.
Bend the frame to the pose first and check it from every angle before adding material, because adjusting a wire under cured putty is not possible. Then build up in stages with epoxy putty, letting each layer cure so the next one has something solid to press against. Steel blades and styluses for the fine work are in sculpting tools, and the rest of the branch — shapers, holders and mould-making supplies — is listed in sculpting tools and materials.
