🔮 Preparation of Base Elements

Before beginning to craft any artifact, gather and cleanse the raw materials. Their quality and purity determine the artifact’s longevity and the effectiveness of its magical charge.

1. Inspect the beech wood and plywood for knots, cracks, and resin inclusions.
2. Check the acrylic sheet for scratches and internal stresses.
3. Ensure the transparent and light-blocking films are free of bubbles and contaminants.
4. Use only new electronic components from reputable suppliers.
5. Clean the magnetic connectors and neodymium magnets with alcohol and activate them with neutral energy.
