Building Blocks

Prismarine building blocks, some of which NauTec machines are built from.

---

Polished Prismarine

The main NauTec building block. Beyond building, it goes into the Aquatic Catalyst, relays, most early machines and the Augmentation Station and Bio Reactor multiblocks.

---

Chiseled Dark Prismarine

A decorative dark prismarine block, one of the blocks the Ocean Ruins arches are built from.

---

Dark Prismarine Pillar

A pillar that faces the way you place it, like a log. The Bio Reactor uses it in its frame.

---

Decorative Prismarine Crystal

A six block tall crystal that glows as brightly as a Sea Lantern. It is purely decorative.

It builds upward from the block you place it in and fills the five blocks above, so it only places where all six blocks are clear. Break any part of it to pick it up: the whole crystal comes down and drops as one item.

Brown Polymer Block

A soft, wool-like block made from Brown Polymer. It crafts back into four polymer.
