Conduit Frame Tiers

Building a Conduit

• Activation frame: 3×3×3 hollow space with the conduit at the center, surrounded by a 5×5×5 shell of valid blocks.
• Valid blocks (any mix): Prismarine, Prismarine Bricks, Dark Prismarine, Sea Lantern.
• Fully submerged: the conduit and the 3×3×3 center MUST be filled with water (flowing or source). Waterlogged blocks count.
• Minimum for activation: 16 blocks (covers the 6 center faces of the 5×5×5 shell).
• Full shell = 42 blocks: gives 96-block effect radius AND hostile-mob attack within 8 blocks of the conduit.
• Effects: Conduit Power = permanent Water Breathing + Night Vision + Haste while underwater in range.

Recipe

Conduit = 1 Heart of the Sea (Treasure Map loot) + 8 Nautilus Shells (drowned / fishing / sell drops).
