Bireme I Blueprint Piece

Obtaining

Recover pieces from eligible NPC loot or trade with other sailors. Equipment blueprint exchanges do not produce ship construction pieces.

The table lists active NPC sources at base rates. Rows marked as independent rolls are separate from the main loot roll; they are not competing alternatives. Eligible loot effects can improve occurrence without changing the rolled rarity.

Construction use

20 pieces are required to construct Bireme at the Shipwright. This piece matches only that family and construction tier. Other blueprint families and tiers cannot replace it.

The full hull recipe also requires Boat Scrap and, for advanced tiers, the separate construction Artifact. See the ship page for its skills and complete recipe.

Storage and trading

Matching items stack in the hold. Carry the required quantity when paying for a service.

Stackable items are withdrawn normally rather than in packed mode.

This item may be traded with another sailor. The Harbour Merchant does not buy it.
