18. Crystal Cavern Fungal Prism
The Crystal Cavern Fungal Prism blends giant mushrooms with massive custom amethyst geodes and tinted glass crystals. Built inside a dark deepslate cavern, the walls are lined with glowing amethyst clusters, purple stained glass spikes, and sea lanterns, creating a dazzling array of purple, magenta, and cyan light reflections. Giant red and brown mushrooms grow inside clear crystal formations, looking like preserved magical specimens caught inside mineral geodes.
The harvesting engine takes advantage of target blocks and observer lines hidden inside the custom crystal spikes surrounding the growing zone. When a mushroom matures and touches the inner crystal walls, redstone signals trigger pulse circuits that break the mushroom blocks via sticky pistons hidden within the amethyst geometry. The falling items gather in glowing water channels flowing over raw iron and gold ore blocks, creating a visually stunning, gemstone-rich mining aesthetic.
